High-current synchronous buck converter suits comms and storage applications

Aimed at applications such as cellular base stations, telecom / network equipment and server / storage systems, ON Semiconductor's NCP3231A high-current synchronous buck converter is now available from Mouser stock. Designed as a high efficiency voltage-mode synchronous buck converter operating from 4.5V to 18V input and generating output voltages down to 0.6V at up to 25A. The device offers lossless low-side FET current sensing, 500KHz switching frequency, external programmable soft-start, output over-voltage and under-voltage protection, system over-temperature protection using a thermistor or sensor through OTS pin, hiccup mode operation for all faults, pre-bias start-up, and an adjustable output voltage, says the company.
