TPS56221EVM-579 Datasheet PDF - TI

●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.

● Input voltage rating from 8V to 14V

● Output voltage rating is 1.0V ±2%

● 25A steady state load current

● 500kHz of switching frequency

● Simple access to power good, enable/soft start and error amplifier

● Convenient converter performance test points

●It is important to operate this EVM within the input voltage range of 8VDC to 14VDC and the output voltage range of 0ADC to 25ADC. Exceeding the specified input range may cause damage to the EVM.
