SA24403 Overview
Description
The SA24403 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 3.5A load current. The SA24403 operates over a wide input voltage range from 4.2V to 40V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
