FEATURES  
DESCRIPTION  
2
4.5-V to 14-V Input Voltage Range  
Incorporates Power Block Technology  
Up to 15-A Output Current  
TPS56121 is  
a high-efficiency and high-current  
synchronous buck converter designed to operate  
from a supply between 4.5 V and 14 V. The device is  
capable of producing an output voltage as low as  
0.6 V at loads up to 15 A. Integrated NexFET  
Power MOSFETs provide a small foot print and ease  
of use.  
Fixed Frequency Options of 300 kHz, 500 kHz  
and 1 MHz  
High-Side and Low-Side MOSFET RDS(on)  
Sensing  
The device implements a voltage-mode control with  
voltage feed-forward compensation that responds  
instantly to input voltage change.  
Programmable Soft-Start  
600-mV Reference Voltage with 1% Accuracy  
Voltage Mode Control with Feed-Forward  
Supports Pre-Biased Output  
TPS56121 is available in a thermally enhanced  
22-pin PQFN (DQP) PowerPADpackage.  
Thermal Shutdown  
The device offers design flexibility with a variety of  
user programmable functions, including soft-start,  
overcurrent protection (OCP) levels, and loop  
compensation. OCP levels are programmed by a  
single external resistor connected from the ILIM pin to  
the circuit ground. During the initial power-on  
sequence, the device enters a calibration cycle,  
measures the voltage at the ILIM pin, and sets an  
internal OCP voltage level. During operation, the  
programmed OCP voltage level is compared to the  
voltage drop across the low-side FET when it is on to  
determine whether there is an overcurrent condition.  
It then enters a shutdown/restart cycle until the fault  
is removed.
