The TPS56221EVM-579 is an evaluation module for TPS56221, a high efficiency and high current synchronous buck converter designed to operate from a supply between 4.5V and 14V. The device is capable of producing an output voltage as low as 0.6V at loads up to 25A. Integrated NexFET power MOSFETs provide a small foot print and ease of use. The device implements a voltage mode control with voltage feed forward compensation that responds instantly to input voltage change. The device offers design flexibility with a variety of user programmable functions, including soft start, overcurrent protection 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.
