TEXAS INSTRUMENTS TPS56221DQPT. 芯片, 同步降压转换器, 14V输入, 12V输出, 25A, 1MHZ, PQFN-22, 整卷
The is a high-efficiency and high-current synchronous Buck Converter designed to operate from a supply of 4.5 to 14V. The device can produce an output voltage as low as 0.6V at loads up to 25A. 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 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.
