Description  
Pin Configuration  
put voltage of the PTH03030W can be  
set to any value over the range 0.8 V to  
2.5 V, using a single resistor.  
The PTH03030 is a series of high-  
current non-isolated power modules  
from Texas Instruments. The product is  
characterized by high efficiencies, and  
up to 30 A of output current, while oc-  
cupying a mere 1.64 in² of PCB area. In  
terms of cost, size, and performance, the  
series provides OEMs with a flexible  
module that meets the requirements of  
the most complex and demanding mixed-  
signal applications. These include the  
most densly populated, multi-processor  
systems that incorporate high-speed  
DSP’s, microprocessors, and ASICs.  
The series uses double-sided surface  
mount construction and provides high-  
performance step-down power conversion  
from a 3.3-V input bus voltage. The out-

Each model also includes an on/off  
inhibit, output voltage adjust (trim), and  
margin up/down controls. An output  
voltage sense ensures tight load regulation,  
and an output over-current and thermal  
shutdown feature provide for protection  
against external load faults.

Pin Descriptions  
Vin: The positive input voltage power node to the mod-

compensate for voltage drop between the module and  
the load. For optimal voltage accuracy Vo Sense should  
be connected to Vout. It can also be left disconnected.  
ule, which is referenced to common GND.  
Vout: The regulated positive power output with respect  
to the GND node.  
Track: This is an analog control input that enables the  
output voltage to follow an external voltage. This pin  
becomes active typically 20 ms after the input voltage  
has been applied, and allows direct control of the output  
voltage from 0 V up to the nominal set-point voltage.  
Within this range the output will follow the voltage at  
the Track pin on a volt-for-volt basis. When the control  
voltage is raised above this range, the module regulates  
at its set-point voltage. The feature allows the output  
voltage to rise simultaneously with other modules pow-  
ered from the same input bus. If unused, this input should  
be connected to Vin. Note: Due to the under-voltage lockout  
feature, the output of the module cannot follow its own input  
voltage during power up. For more information, consult the  
related application note.  
GND: This is the common ground connection for the  
Vin and Vout power connections. It is also the 0 VDC  
reference for the control inputs.  
Inhibit: The Inhibit pin is an open-collector/drain negative  
logic input that is referenced to GND. Applying a low-  
level ground signal to this input disables the modules  
output and turns off the output voltage. When the Inhibit  
control is active, the input current drawn by the regula-  
tor is significantly reduced. If the Inhibit pin is left  
open-circuit, the module will produce an output when-  
ever a valid input source is applied.  
Vo Adjust: A 0.1 W 1 % resistor must be directly connected  
between this pin and pin 7 (GND) to set the output voltage  
to a value higher than 0.8 V. The temperature stability of  
the resistor should be 100 ppm/°C (or better). The set  
point range for the output voltage is from 0.8 V to 2.5 V.  
The resistor value required for a given output voltage  
may be calculated from the following formula. If left  
open circuit, the output voltage will default to its lowest  
value. For further information on output voltage adjust-  
ment consult the related application note.  
Margin Down: When this input is asserted to GND, the  
output voltage is decreased by 5% from the nominal. The  
input requires an open-collector (open-drain) interface.  
It is not TTL compatible. A lower percent change can  
be accomodated with a series resistor. For further infor-  
mation, consult the related application note.  
Margin Up: When this input is asserted to GND, the  
output voltage is increased by 5%. The input requires an  
open-collector (open-drain) interface. It is not TTL  
compatible. The percent change can be reduced with a  
series resistor. For further information, consult the  
related application note.

Notes: (1) See SOA curves or consult factory for appropriate derating.  
(2) The minimum input voltage is equal to 2.95 V or Vout + 0.5 V, whichever is greater.  
(3) The set-point voltage tolerance is affected by the tolerance and stability of RSET. The stated limit is unconditionally met if RSET has a tolerance of 1 %  
with 100 ppm/°C or better temperature stability.  
(4) A small low-leakage (<100 nA) MOSFET is recommended to control this pin. The open-circuit voltage is less than 1 Vdc.  
(5) This control pin has an internal pull-up to the input voltage Vin. If it is left open-circuit the module will operate when input power is applied. A small  
low-leakage (<100 nA) MOSFET is recommended for control. For further information, consult the related application note.  
(6) A 1,500 µF electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 900 mA rms of ripple current.  
(7) An external output capacitor is not required for basic operation. Adding 330 µF of distributed capacitance at the load will improve the transient response.  
(8) This is the calculated maximum. The minimum ESR limitation will often result in a lower value. Consult the application notes for further guidance.  
(9) This is the typical ESR for all the electrolytic (non-ceramic) output capacitance. Use 7 mas the minimum when using max-ESR values to calculate.

PTH03030W & PTH05030W  
Capacitor Recommendations for the PTH03030 &  
PTH05030 Series of Power Modules  
Input Capacitor  
dissipation, and ripple current capability. As a caution  
many general purpose tantalum capacitors have consider-  
ably higher ESR, reduced power dissipation and lower  
ripple current capability. These capacitors are also less  
reliable when determining their power dissipation and  
surge current capability. Tantalum capacitors that do  
not have a stated ESR or surge current rating are not  
recommended for power applications.  
The recommended input capacitor(s) is determined by  
the 1,500 µF (1) minimum capacitance and 900 mArms  
minimum ripple current rating.  
Ripple current and <100 mequivalent series resistance  
(ESR) values are the major considerations, along with  
temperature, when designing with different types of  
capacitors. Unlike polymer tantalum, conventional tan-  
talum capacitors have a recommended minimum voltage  
rating of 2 × (maximum DC voltage + AC ripple). This  
is standard practice to ensure reliability.  
When specifying Os-Con and polymer tantalum capacitors  
for the output, the minimum ESR limit will be encoun-  
tered well before the maximum capacitance value is  
reached.  
For improved ripple reduction on the input bus, ceramic  
capacitors may be used to complement electrolytic types  
and achieve the minimum required capacitance.  
Capacitor Table  
Table 1-1 identifies the characteristics of capacitors from a  
number of vendors with acceptable ESR and ripple current  
(rms) ratings. The recommended number of capacitors  
required at both the input and output buses is identified  
for each capacitor type.  
Output Capacitors (Optional)  
For applications with load transients (sudden changes in  
load current), regulator response will benefit from an  
external output capacitance. The recommended output  
capacitance of 330 µF will allow the module to meet  
its transient response specification (see product data sheet).  
For most applications, a high quality computer-grade  
aluminum electrolytic capacitor is most suitable. These  
capacitors provide adequate decoupling over the frequency  
range, 2 kHz to 150 kHz, and are suitable when ambient  
temperatures are above 0 °C. For operation below 0 °C,  
tantalum, ceramic or Os-Con type capacitors are recom-  
mended. When using one or more non-ceramic capacitors,  
the calculated equivalent ESR should be no lower than  
4 m(7 musing the manufacturers maximum ESR  
for a single capacitor). A list of preferred low-ESR type  
capacitors are identified in Table 1-1.  
This is not an extensive capacitor list. Capacitors from other  
vendors are available with comparable specifications. Those  
listed are for guidance. The RMS ripple current rating and  
ESR (at 100kHz) are critical parameters necessary to insure  
both optimum regulator performance and long capacitor life.  
Designing for Very Fast Load Transients  
The transient response of the DC/DC converter has been  
characterized using a load transient with a di/dt of 1 A/µs.  
The typical voltage deviation for this load transient is  
given in the data sheet specification table using the  
optional value of output capacitance. As the di/dt of a  
transient is increased, the response of a converters regu-  
lation circuit ultimately depends on its output capacitor  
decoupling network. This is an inherent limitation with  
any DC/DC converter once the speed of the transient  
exceeds its bandwidth capability. If the target application  
specifies a higher di/dt or lower voltage deviation, the  
requirement can only be met with additional output  
capacitor decoupling. In these cases special attention  
must be paid to the type, value and ESR of the capacitors  
selected.  
Ceramic Capacitors  
Above 150 kHz the performance of aluminum electrolytic  
capacitors becomes less effective. To further improve the  
reflected input ripple current or the output transient  
response, multilayer ceramic capacitors can also be added.  
Ceramic capacitors have very low ESR and their resonant  
frequency is higher than the bandwidth of the regulator.  
When used on the output their combined ESR is not  
critical as long as the total value of ceramic capacitance  
does not exceed 300 µF. Also, to prevent the formation of  
local resonances, do not place more than five identical ce-  
ramic capacitors in parallel with values of 10 µF or greater.  
If the transient performance requirements exceed that  
specified in the data sheet, or the total amount of load  
capacitance is above 3,000 µF, the selection of output  
capacitors becomes more important. For further guidance  
consult the separate application note, “Selecting Capaci-  
tors for PTH Products in High-Performance Applications.”  
Tantalum Capacitors  
Tantalum type capacitors can be used at both the input  
and output, and are recommended for applications where  
the ambient operating temperature can be less than 0 °C.  
The AVX TPS, Sprague 593D/594/595 and Kemet T495/  
T510 capacitor series are suggested over many other  
tantalum types due to their higher rated surge, power

PTH Series of Wide-Output Adjust  
Power Modules (3.3/5-V Input)  
Features of the PTH Family of Non-Isolated  
Wide Output Adjust Power Modules  
output current, PTHxx020W and PTHxx030W products  
incorporate over-temperature shutdown protection. All  
of the products referenced in Table 3-1 include Auto-  
Track™. This is a feature unique to the PTH family,  
and was specifically designed to simplify the task of se-  
quencing the supply voltage in a power system. These  
and other features are described in the following sections.  
Point-of-Load Alliance  
The PTH family of non-isolated, wide-output adjust  
power modules from Texas Instruments are optimized  
for applications that require a flexible, high performance  
module that is small in size. These products are part of  
the “Point-of-Load Alliance” (POLA), which ensures  
compatible footprint, interoperability and true second  
sourcing for customer design flexibility. The POLA is a  
collaboration between Texas Instruments, Artesyn Tech-  
nologies, and Astec Power to offer customers advanced  
non-isolated modules that provide the same functionality  
and form factor. Product series covered by the alliance  
includes the PTHxx050W (6 A), PTHxx060W (10 A),  
PTHxx010W (15/12 A), PTHxx020W (22/18 A), and  
the PTHxx030W (30/26 A).  
Soft-Start Power Up  
The Auto-Track feature allows the power-up of multiple  
PTH modules to be directly controlled from the Track  
pin. However in a stand-alone configuration, or when  
the Auto-Track feature is not being used, the Track pin  
should be directly connected to the input voltage, Vin  
(see Figure 3-1).  
Figure 3–1  
From the basic, “Just Plug it In” functionality of the 6-A  
modules, to the 30-A rated feature-rich PTHxx030W,  
these products were designed to be very flexible, yet simple  
to use. The features vary with each product. Table 3-1  
provides a quick reference to the available features by  
product and input bus voltage.

When the Track pin is connected to the input voltage the

at a quicker and more linear rate.

PTH Series of Wide-Output Adjust  
Power Modules (3.3/5-V Input)  
The power modules function normally when the Inhibit  
pin is left open-circuit, providing a regulated output  
whenever a valid source voltage is connected to Vin with  
respect to GND.  
From the moment a valid input voltage is applied, the  
soft-start control introduces a short time delay (typically  
5 ms-10 ms) before allowing the output voltage to rise.  
The output then progressively rises to the modules set-  
point voltage. Figure 3-2 shows the soft-start power-up  
characteristic of the 22-A output product (PTH05020W),  
operating from a 5-V input bus and configured for a 3.3-V  
output. The waveforms were measured with a 5-A resistive  
load, with Auto-Track disabled. The initial rise in input  
current when the input voltage first starts to rise is the  
charge current drawn by the input capacitors. Power-up  
is complete within 15 ms.  
Figure 3-3 shows the typical application of the inhibit  
function. Note the discrete transistor (Q1). The Inhibit  
control has its own internal pull-up to Vin potential. The  
input is not compatible with TTL logic devices. An open-  
collector (or open-drain) discrete transistor is recommended  
for control.  
Figure 33  
Vo Sense  
Over-Current Protection  
For protection against load faults, all modules incorporate  
output over-current protection. Applying a load that  
exceeds the regulators over-current threshold will cause  
the regulated output to shut down. Following shutdown  
a module will periodically attempt to recover by initiating  
a soft-start power-up. This is described as a “hiccup” mode  
of operation, whereby the module continues in a cycle of  
successive shutdown and power up until the load fault is  
removed. During this period, the average current flowing  
into the fault is significantly reduced. Once the fault is  
removed, the module automatically recovers and returns  
to normal operation.

Over-Temperature Protection  
Turning Q1 on applies a low voltage to the Inhibit control  
and disables the output of the module. If Q1 is then turned  
off, the module will execute a soft-start power-up. A  
regulated output voltage is produced within 20 msec.  
Figure 3-4 shows the typical rise in both the output volt-  
age and input current, following the turn-off of Q1. The  
turn off of Q1 corresponds to the rise in the waveform,  
Q1 Vds. The waveforms were measured with a 5-A load.  
The PTHxx020 and PTHxx030 series of products have  
over-temperature protection. These products have an  
on-board temperature sensor that protects the modules  
internal circuitry against excessively high temperatures.  
A rise in the internal temperature may be the result of a  
drop in airflow, or a high ambient temperature. If the  
internal temperature exceeds the OTP threshold, the  
modules Inhibit control is automatically pulled low. This  
turns the output off. The output voltage will drop as the  
external output capacitors are discharged by the load  
circuit. The recovery is automatic, and begins with a  
soft-start power up. It occurs when the the sensed tem-  
perature decreases by about 10 °C below the trip point.  
Figure 34  
Note: The over-temperature protection is a last resort mecha-  
nism to prevent thermal stress to the regulator. Operation at  
or close to the thermal shutdown temperature is not recom-  
mended and will reduce the long-term reliability of the module.  
Always operate the regulator within the specified Safe Operating  
Area (SOA) limits for the worst-case conditions of ambient  
temperature and airflow.

PTH Series of Wide-Output Adjust  
Power Modules (3.3/5-V Input)  
Auto-TrackFunction  
The Auto-Track function is unique to the PTH family,  
and is available with the all “Point-of-Load Alliance”  
(POLA) products. Auto-Track was designed to simplify  
the amount of circuitry required to make the output  
voltage from each module power up and power down in  
sequence. The sequencing of two or more supply voltages  
during power up is a common requirement for complex  
mixed-signal applications, that use dual-voltage VLSI ICs  
such as DSPs, micro-processors, and ASICs.  
other modules, to its respective set-point voltage.  
Figure 3-6 shows the output voltage waveforms from the  
circuit of Figure 3-5 after the On/Off Control is set from a  
high to a low-level voltage. The waveforms, Vo1 and Vo2  
represent the output voltages from the two power mod-  
ules, U1 (3.3 V) and U2 (1.8 V) respectively. Vo1 and Vo2  
are shown rising together to produce the desired simul-  
taneous power-up characteristic.  
The same circuit also provides a power-down sequence.  
Power down is the reverse of power up, and is accom-  
plished by lowering the track control voltage back to zero  
volts. The important constraint is that a valid input voltage  
must be maintained until the power down is complete. It  
also requires that Q1 be turned off relatively slowly. This  
is so that the Track control voltage does not fall faster than  
Auto-Track's slew rate capability, which is 1 V/ms. The  
components R1 and C1 in Figure 3-5 limit the rate at  
which Q1 can pull down the Track control voltage. The  
values of 100 k-ohm and 0.1 µF correlate to a decay rate  
of about 0.17 V/ms.  
How Auto-Track Works  
Auto-Track works by forcing the modules output voltage  
to follow a voltage presented at the Track control pin. This  
control range is limited to between 0 V and the modules  
set-point voltage. Once the track-pin voltage is raised  
above the set-point voltage, the modules output remains  
1
at its set-point . As an example, if the Track pin of a 2.5-V  
regulator is at 1 V, the regulated output will be 1 V. But  
if the voltage at the Track pin rises to 3 V, the regulated  
output will not go higher than 2.5 V.  
When under track control, the regulated output from  
the module follows the voltage at its Track pin on a volt-  
for-volt basis. By connecting the Track pin of a number  
of these modules together, the output voltages will fol-  
low a common signal during power-up and power-down.  
The control signal can be an externally generated master  
ramp waveform, or the output voltage from another power  
supply circuit 3. For convenience the Track control incor-  
porates an internal RC charge circuit. This operates off  
the modules input voltage to provide a suitable rising  
voltage ramp waveform.  
The power-down sequence is initiated with a low-to-high  
transition at the On/Off Control input to the circuit.  
Figure 3-7 shows the power-down waveforms. As the  
Track control voltage falls below the nominal set-point  
voltage of each power module, then its output voltage  
decays with all the other modules under Auto-Track  
control.  
Notes on Use of Auto-Track™  
1.The Track pin voltage must be allowed to rise above  
the modules set-point voltage before the module can  
regulate at its adjusted set-point voltage.  
Typical Application  
The basic implementation of Auto-Track allows for  
simultaneous voltage sequencing of a number of Auto-  
Track compliant modules. Connecting the Track control  
pins of two or more modules forces the Track control of  
all modules to follow the same collective RC ramp wave-  
form, and allows them to be controlled through a single  
transistor or switch; Q1 in Figure 3-5.  
2.The Auto-Track function will track almost any voltage  
ramp during power up, and is compatible with ramp  
speeds of up to 1 V/ms.  
3. The absolute maximum voltage that may be applied to the  
Track pin is Vin.  
4.The module will not follow  
a voltage at its Track control  
To initiate a power-up sequence the Track control must  
first pulled to ground potential. This should be done at  
or before input power is applied to the modules, and then  
held for at least 10 ms thereafter. This brief period gives  
the modules time to complete their internal soft-start  
initialization, which enables them to produce an output  
voltage.  
input until it has completed its soft-start initialization.  
This takes about 10 ms from the time that the module  
has sensed that a valid voltage has been applied its input.  
During this period, it is recommended that the Track  
pin be held at ground potential.  
5.The module is capable of both sinking and sourcing  
current when following a voltage at its Track pin.  
Therefore startup into an output prebias is not supported  
during Auto-Track control. Note: A pre-bias holdoff is  
not necessary when all supply voltages rise simultaneously  
under the control of Auto-Track.  
Applying a logic-level high signal to the circuits On/Off  
Control turns Q1 on and applies a ground signal to the  
Track control. After completing their internal soft-start  
intialization, the output of all modules will remain at zero  
volts while Q1 is on. 10 ms after a valid input voltage has  
been applied to all modules, Q1 can be turned off. This  
allows the track control voltage to automatically rise  
toward to the modules' input voltage. During this period  
the output voltage of each module will rise in unison with  
6.The Auto-Track functioncan be disabled by connecting  
the Track pin to the input voltage (Vin). With Auto-Track  
disabled, the output voltage will rise at a quicker and  
more linear rate after input power is applied.

Notes:  
Margin Up/Down Controls  
The PTHxx060W, PTHxx010W, PTHxx020W, and  
PTHxx030W products incorporate Margin Up and Margin  
Down control inputs. These controls allow the output  
1.The Margin Up* and Margin Dn* controls were not  
intended to be activated simultaneously. If they are  
their affects on the output voltage may not completely  
cancel, resulting in the possibility of a slightly higher  
error in the output voltage set point.

voltage to be momentarily adjusted , either up or down,  
by a nominal 5 %. This provides a convenient method  
for dynamically testing the operation of the load circuit  
over its supply margin or range. It can also be used to verify  
the function of supply voltage supervisors. The 5 %  
change is applied to the adjusted output voltage, as set by  
the external resistor, Rset at the Vo Adjust pin.  
2.The ground reference should be  
a direct connection to  
the module GND at pin 7 (pin 1 for the PTHxx050).  
This will produce a more accurate adjustment at the  
load circuit terminals. The transistors Q1 and Q2 should  
be located close to the regulator.  
The 5 % adjustment is made by pulling the appropriate  
margin control input directly to the GND terminal .

3.The Margin Up and Margin Dn control inputs are not  
compatible with devices that source voltage. This includes  
TTL logic. These are analog inputs and should only be  
controlled with a true open-drain device (preferably  
a discrete MOSFET transistor). The device selected  
should have low off-state leakage current. Each input  
sources 8 µA when grounded, and has an open-circuit  
voltage of 0.8 V.  
A low-leakage open-drain device, such as an n-channel  
MOSFET or p-channel JFET is recommended for this  
3
purpose . Adjustments of less than 5 % can also be accom-  
modated by adding series resistors to the control inputs.  
The value of the resistor can be selected from Table 3-2,  
or calculated using the following formula.  
Up/Down Adjust Resistance Calculation  
To reduce the margin adjustment to something less than  
5 %, series resistors are required (See RD and RU in  
Figure 3-8). For the same amount of adjustment, the  
resistor value calculated for RU and RD will be the same.  
The formulas is as follows.

Power Modules (3.3/5-V Input)  
Notes  
Pre-Bias Startup Capability  
Only selected products in the PTH family incorporate this  
capability. Consult Table 3-1 to identify which products  
are compliant.  
1.Startup includes the short delay (approx. 10 ms) prior  
to the output voltage rising, followed by the rise of the  
output voltage under the module’s internal soft-start  
control. Startup is complete when the output voltage  
has risen to either the set-point voltage or the voltage  
at the Track pin, whichever is lowest.  
A pre-bias startup condition occurs as a result of an external  
voltage being present at the output of a power module prior  
to its output becoming active. This often occurs in com-  
plex digital systems when current from another power  
source is backfed through a dual-supply logic component,  
such as an FPGA or ASIC. Another path might be via  
clamp diodes as part of a dual-supply power-up sequencing  
arrangement. A prebias can cause problems with power  
modules that incorporate synchronous rectifiers. This is  
because under most operating conditions, these types of  
modules can sink as well as source output current.  
2.To ensure that the regulator does not sink current when  
power is first applied (even with a ground signal applied  
to the Inhibit control pin), the input voltage must always  
be greater than the output voltage throughout the  
power-up and power-down sequence.  
3.The Auto-Track function can be disabled at power up  
by immediately applying a voltage to the modules Track  
pin that is greater than its set-point voltage. This can  
be easily accomplished by connecting the Track pin to  
Vin.  
The PTH family of power modules incorporate synchro-  
1
nous rectifiers, but will not sink current during startup ,  
or whenever the Inhibit pin is held low. However, to ensure  
satisfactory operation of this function, certain conditions  
must be maintained. Figure 3-9 shows an application  
Figure 310; Pre-Bias Startup Waveforms  
2
demonstrating the pre-bias startup capability. The start-  
up waveforms are shown in Figure 3-10. Note that the  
output current from the PTH03010W (Io) shows negli-  
gible current until its output voltage rises above that  
backfed through diodes D1 and D2.  
Vin (1 V/Div)  
Vo (1 V/Div)  
Note: The pre-bias start-up feature is not compatible with  
Auto-Track. When the module is under Auto-Track control,  
it will sink current if the output voltage is below that of a  
back-feeding source. To ensure a pre-bias hold-off one of two  
approaches must be followed when input power is applied to  
Io (5 A/Div)  
3
the module. The Auto-Track function must either be disabled ,  
or the module’s output held off (for at least 50 ms) using the  
Inhibit pin. Either approach ensures that the Track pin volt-  
age is above the set-point voltage at start up.

PTH Series of Wide-Output Adjust  
Power Modules (3.3/5-V Input)  
Remote Sense  
The PTHxx060W, PTHxx010W, PTHxx020W, and  
PTHxx030W products incorporate an output voltage  
sense pin, Vo Sense. The Vo Sense pin should be connected  
to Vout at the load circuit (see data sheet standard appli-  
cation). A remote sense improves the load regulation  
performance of the module by allowing it to compensate  
for any ‘IR’ voltage drop between itself and the load. An  
IR drop is caused by the high output current flowing  
through the small amount of pin and trace resistance.  
Use of the remote sense is optional. If not used, the  
Vo Sense pin can be left open-circuit. An internal low-  
value resistor (15-or less) is connected between the  
Vo Sense and Vout. This ensures the output voltage remains  
in regulation.  
With the sense pin connected, the difference between  
the voltage measured directly between the Vout and GND  
pins, and that measured from Vo Sense to GND, is the  
amount of IR drop being compensated by the regulator.  
This should be limited to a maximum of 0.3 V.  
Note: The remote sense feature is not designed to compensate  
for the forward drop of non-linear or frequency dependent  
components that may be placed in series with the converter  
output. Examples include OR-ing diodes, filter inductors,  
ferrite beads, and fuses. When these components are enclosed  
by the remote sense connection they are effectively placed  
inside the regulation control loop, which can adversely affect  
the stability of the regulator.
