SA24403 Overview
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. The SA24403 adopts peak current control scheme.
