Description

The SC462H is a high performance synchronous buck

controller that can be configured for a wide range of

applications. The SC462H utilizes synchronous rectified

buck topology where high efficiency is the primary con-

sideration. SC462H can be used over a wide input voltage

range with output voltage adjustable within limits set by

the duty cycle boundaries.

SC462H comes with a rich set of features such as regu-

lated DRV supply, programmable soft-start, high current

gate drivers, shoot through protection, R

DS(ON) sensing with

hiccup over current protection.
