In the case of where the switch mode approaches 100% duty  
cycle for the high side FET, the device automatically reduces  
the duty cycle switch to a minimum off time on every 8th cycle  
to allow this capacitor to re-charge  
Functional Description  
The TS30011/12/13 current-mode synchronous step-down  
regulator 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 reduce the external component  
count and 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.  
Sense feedback, FB  
This is the input terminal for the output voltage feedback.  
For the fixed output versions, this should be hooked directly to  
VOUT. The PCB connection should be kept as short as possible,  
and should be made as close as possible to the output  
capacitor. The trace should not be shared with any other  
connection. (Figure 24)  
For adjustable output versions, the FB input should be  
connected to the external resistor divider. To choose the  
resistors, use the following equation:  
The TS30011/12/13 provides these system benefits:  
VOUT = 0.9 (1 + RTOP/RBOT  
)
Reduced board real estate  
Lower system cost  
The FB input 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 with minimum width to reduce stray capacitance  
and to reduce the injection of noise.

Switching output, VSW  
This is the switching node of the regulator. It should be  
connected directly to the 4.7uH inductor with a wide, short  
trace and also to one end of the Bootstrap capacitor. This node  
switches between VCC and PGND at the switching frequency.  
Detailed Pin Description  
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.  
Ground, GND  
This ground is used for the majority of the device including the  
analog reference, control loop, and other circuits.  
Power Ground, PGND  
Bootstrap control, BST  
This is a separate power ground connection used for the low-  
side synchronous switch, to isolate switching noise from the  
rest of the device. (Figure 24)  
This terminal provides 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 provides the necessary voltage for the upper  
switch. In normal operation the capacitor is recharged on  
every switching cycle when the low-side NMOS is on.  
Enable, 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.

Power Good Output, PG  
Output Overvoltage  
This is an open drain output. During start-up the FB input is  
monitored and the PG line remains low, until the FB voltage  
reaches the VOUT_UV threshold. A 10KΩ resistor to VOUT is  
required for pull-up. Once the internal comparator detects  
that the FB 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 of a fault, when the  
FB voltage decreases below VOUT_UV, the PG line asserts low and  
remains low until the FB input exceeds VOUT_UV and the delay  
timer times out. See Figure 3 for the control of the PG signal.  
If the FB input 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.  
Internal Protection Details  
Internal Current Limit  
Transient Response  
The high-side NMOS current is sensed on a cycle by cycle basis  
and if current limit is reached, the IC truncates the high-side  
on-time. The device also senses the FB pin to identify hard  
output shorts or extended over-current conditions. It then  
directs the VSW output to skip 4 cycles and frequency will  
foldback to 250KHz, 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.  
TS30011/12/13 has been designed to work under a wide range  
of input and output voltages, supporting different values and  
types of output capacitance. By design, the TS30011/12/13  
has a lower control loop bandwidth. For designs with a high  
slew rate load requirement, using a 1nF feed-forward capacitor  
CFF (Figure 23) in parallel with RTOP feedback resistor is recom-  
mended. A typical response is shown in Figure 22.  
Figure 22. 100mA to 2A Load Step  
(Load Slew Rate=2.5A/us, VCC=12V, VOUT=4V)  
Once the over current condition is removed, the device returns  
to normal operation automatically. (Alternately the factory can  
configure the device to shutdown the regulator if an extended  
over current event is detected, which requires a toggle of the  
Enable pin to return the device to normal operation. Contact  
Semtech Marketing for specific information.)  
Thermal Shutdown  
If the die temperature exceeds 170°C (typical), the VSW  
outputs will tri-state to protect the device from damage. The  
PG and all other protection circuitry 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 die again reaches 170°C, the  
shutdown/restart sequence will repeat.  
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.

Typical Application Schematic  
Figure 23: TS30011/12/13 Application Schematic  
A minimal schematic suitable for most applications is shown on page 1. Figure 23 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 24) The main guidelines are the following:  
provide low inductive and resistive paths for loops with high di/dt or high dV/dt,  
provide low capacitive paths with respect to all the other nodes for traces with high di/dt or high dV/dt,  
sensitive nodes not assigned to power transmission should be referenced to the analog signal ground (GND) and should  
always be 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, CBYPASS2) 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, RBOT and RTOP are not required and the FB pin should connect directly to VOUT  
.

Note 1:  
The voltage divider resistor values are calculated for an output voltage of 2.5V. For fixed output versions, the FB pin is connected directly to 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 regulator 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 applications, the optional Schottky diode DCATCH improves overall efficiency and reduces 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 versions, 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.  
RPLP 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 with multiple 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.
