TPS56221DQPT / LSON-22 / Power Management ICs
The TPS56221 device is a high-efficiency and highcurrent synchronous buck converter designed to operate from a supply from 4.5 V to 14 V. The device can produce an output voltage as low as 0.6 V at loads up to 25 A. Integrated NexFET™ Power MOSFETs provide a small footprint and ease of use.
The device implements a voltage-mode control with voltage feed-forward compensation that responds instantly to input voltage change.
The TPS56221 is available in a thermally enhanced 22-pin PQFN (DQP) PowerPAD package.
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.
