Functional Description
Detailed Pin Description
The TS30011/12/13 current-mode synchronous step-down
power supply product is ideal for use in the commercial,
industrial, and automotive market segments. It includes
flexibility to be used for a wide range of output voltages and
is optimized for high efficiency power conversion with low
RDSON integrated synchronous switches. A 1MHz internal
switching frequency facilitates low cost LC filter combinations.
Additionally, the fixed output versions enable a minimum
external component count to provide a complete regulation
solution with only 4 external components: an input bypass
capacitor, an inductor, an output capacitor, and the bootstrap
capacitor. The regulator automatically transitions between
PFM and PWM mode to maximize efficiency for the load
demand.
Unregulated input, VCC
This terminal is the unregulated input voltage source for the
IC. It is recommended that a 10uF bypass capacitor be placed
close to the device for best performance. Since this is the main
supply for the IC, good layout practices need to be followed for
this connection.
Bootstrap control, BST
This terminal will provide the bootstrap voltage required for
the upper internal NMOS switch of the buck regulator. An
external ceramic capacitor placed between the BST input
terminal and the VSW pin will provide the necessary voltage
for the upper switch. In normal operation the capacitor is
re-charged on every low side synchronous switching action.
In the case of where the switch mode approaches 100% duty
cycle for the high side FET, the device will automatically reduce
the duty cycle switch to a minimum off time on every 8th cycle
to allow this capacitor to re-charge.
The TS30011/12/13 was designed to provide these system
benefits:
•
Reduced board real estate
•
Lower system cost
Sense feedback, FB
This is the input terminal for the output voltage feedback.
Lower cost inductor
Low external parts count
•
•
Ease of design
For the fixed mode versions, this should be hooked directly
to VOUT. The connection on the PCB should be kept as short
as possible, and should be made as close as possible to the
capacitor. The trace should not be shared with any other
connection. (Figure 23)

Over current, over voltage and over temperature
protection
For adjustable mode versions, this should be connected to
the external resistor divider. To choose the resistors, use the
following equation:
VOUT = 0.9 (1 + RTOP/RBOT
)
The input to the FB pin is high impedance, and input current
should be less than 100nA. As a result, good layout practices
are required for the feedback resistors and feedback traces.
When using the adjustable version, the feedback trace should
be kept as short as possible and minimum width to reduce
stray capacitance and to reduce the injection of noise.
For the adjustable version, the ratio of VCC/VOUT cannot
exceed 16.

Internal Protection Details
Switching output, VSW
Internal Current Limit
This is the switching node of the regulator. It should be
connected directly to the 4.7uH inductor with a wide, short
trace and to one end of the Bootstrap capacitor. It is switching
between VCC and PGND at the switching frequency.
The current through the high side FET is sensed on a cycle
by cycle basis and if current limit is reached, it will abbreviate
the cycle. In addition, the device senses the FB pin to identify
hard short conditions and will direct the VSW output to skip 4
cycles if current limit occurs when FB is low. This allows current
built up in the inductor during the minimum on time to decay
sufficiently. Current limit is always active when the regulator
is enabled. Soft start ensures current limit does not prevent
regulator startup.
Ground, GND
This ground is used for the majority of the device including the
analog reference, control loop, and other circuits.
Power Ground, PGND
This is a separate ground connection used for the low side
synchronous switch to isolate switching noise from the rest of
the device. (Figure 23)
Under extended over current conditions (such as a short),
the device will automatically disable. Once the over current
condition is removed, the device returns to normal operation
automatically. (Alternately the factory can configure the
device’s NVM to shutdown the regulator if an extended over
current event is detected and require a toggle of the Enable
pin to return the device to normal operation.)
Enable, high-voltage, EN
This is the input terminal to activate the regulator. The input
threshold is TTL/CMOS compatible. It also has an internal pull-
up to ensure a stable state if the pin is disconnected.
Thermal Shutdown
Power Good Output, PG
If the temperature of the die exceeds 170°C (typical), the VSW
outputs will tri-state to protect the device from damage. The
PG and all other protection circuitry will stay active to inform
the system of the failure mode. Once the device cools to 160°C
(typical), the device will start up again, following the normal
soft start sequence. If the device reaches 170°C, the shutdown/
restart sequence will repeat.
This is an open drain, active low output. The switched mode
output voltage is monitored and the PG line will remain low
until the output voltage reaches the VOUT-UV threshold.
Once the internal comparator detects the output voltage
is above the desired threshold, an internal delay timer is
activated and the PG line is de-asserted to high once this
delay timer expires. In the event the output voltage decreases
below VOUT-UV, the PG line will be asserted low and remain
low until the output rises above VOUT-UV and the delay timer
times out. See Figure 2 for the circuit schematic for the PG
signal.
Reference Soft Start
The reference in this device is ramped at a rate of 4ms to
prevent the output from overshoot during startup. This ramp
restarts whenever there is a rising edge sensed on the Enable
pin. This occurs in both the fixed and adjustable versions.
During the soft start ramp, current limit is still active, and will
still protect the device in case of a short on the output.
Output Overvoltage
If the output of the regulator exceeds 103% of the regulation
voltage, the VSW outputs will tri-state to protect the device
from damage. This check occurs at the start of each switching
cycle. If it occurs during the middle of a cycle, the switching
for that cycle will complete, and the VSW outputs will tri-state
at the beginning of the next cycle.
VCC Under-Voltage Lockout
The device is held in the off state until VCC reaches 4.5V
(typical). There is a 500mV hysteresis on this input, which
requires the input to fall below 4.0V (typical) before the device
will disable.

A minimal schematic suitable for most applications is shown on page 1. Figure 22 includes optional components that may be
considered to address specific issues as listed in the External Component Selection section.
PCB Layout
For proper operation and minimum EMI, care must be taken during PCB layout. An improper layout can lead to issues such as poor
stability and regulation, noise sensitivity and increased EMI radiation. (figure 23) The main guidelines are the following:
•
•
•
provide low inductive and resistive paths for loops with high di/dt,
provide low capacitive paths with respect to all the other nodes for traces with high di/dt,
sensitive nodes not assigned to power transmission should be referenced to the analog signal ground (GND) and be always
separated from the power ground (PGND).
The negative ends of CBYPASS, COUT and the Schottky diode DCATCH (optional) should be placed close to each other and
connected using a wide trace. Vias must be used to connect the PGND node to the ground plane. The PGND node must be placed
as close as possible to the TS30011/12/13 PGND pins to avoid additional voltage drop in traces.
The bypass capacitor CBYPASS (optionally paralleled to a 0.1µF capacitor) must be placed close to the VCC pins of TS30011/12/13.
The inductor must be placed close to the VSW pins and connected directly to COUT in order to minimize the area between the
VSW pin, the inductor, the COUT capacitor and the PGND pins. The trace area and length of the switching nodes VSW and BST
should be minimized.
For the adjustable output voltage version of the TS30011/12/13, feedback resistors RBOT and RTOP are required for Vout settings
greater than 0.9V and should be placed close to the TS30011/12/13 in order to keep the traces of the sensitive node FB as short as
possible and away from switching signals. RBOT should be connected to the analog ground pin (GND) directly and should never
be connected to the ground plane. The analog ground trace (GND) should be connected in only one point to the power ground
(PGND). A good connection point is under the TS30011/12/13 package to the exposed thermal pad and vias which are connected
to PGND. RTOP will be connected to the VOUT node using a trace that ends close to the actual load.
For fixed output voltage versions of the TS30011/12/13, RBOT and RTOP are not required and the FB pin should be connected
directly to the Vout.

External Component Selection
The 1MHz internal switching frequency of the TS30011/12/13 facilitates low cost LC filter combinations. Additionally, the fixed
output versions enable a minimum external component count to provide a complete regulation solution with only 4 external
components: an input bypass capacitor, an inductor, an output capacitor, and the bootstrap capacitor. The internal compensation
is optimized for a 44uF output capacitor and a 4.7uH inductor.
For best performance, a low ESR ceramic capacitor should be used for CBYPASS. If CBYPASS is not a low ESR ceramic capacitor, a
0.1uF ceramic capacitor should be added in parallel to CBYPASS.
The minimum allowable value for the output capacitor is 33uF. To keep the output ripple low, a low ESR (less than 35mOhm)
ceramic is recommended. Multiple capacitors can be paralleled to reduce the ESR.
The inductor range is 4.7uH +/-20%. For optimal over-current protection, the inductor should be able to handle up to the
regulator current limit without saturation. Otherwise, an inductor with a saturation current rating higher than the maximum IOUT
load requirement plus the inductor current ripple should be used.
For high current modes, the optional Schottky diode will improve the overall efficiency and reduce the heat. It is up to the user to
determine the cost/benefit of adding this additional component in the user’s application. The diode is typically not needed.
For the adjustable output version of the TS30011/12/13, the output voltage can be adjusted by sizing RTOP and RBOT feedback
resistors. The equation for the output voltage is
For the adjustable version, the ratio of VCC/Vout cannot exceed 16.
RPUP is only required when the Power Good signal (PG) is utilized.
Thermal Information
TS30011/12/13 is designed for a maximum operating junction temperature Tj of 125°C. The maximum output power is limited by
the power losses that can be dissipated over the thermal resistance given by the package and the PCB structures. The PCB must
provide heat sinking to keep the TS30011/12/13 cool. The exposed metal on the bottom of the QFN package must be soldered to
a ground plane. This ground should be tied to other copper layers below with thermal vias. Adding more copper to the top and
the bottom layers and tying this copper to the internal planes with vias can reduce thermal resistance further. For a hi-K JEDEC

board and 13.5 square inch of 1 oz Cu, the thermal resistance from junction to ambient can be reduced to θ = 38°C/W. The
power dissipation of other power components (catch diode, inductor) cause additional copper heating andJAcan further increase
what the TS30011/12/13 sees as ambient temperature.
