SY8303 Overview
The SY8303 develops a high efficiency synchronous step-down DC-DC converter capable of delivering 3A load current. The SY8303 operates over a wide input voltage range from 4.5V to 40V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SY8303 adopts peak current control scheme.
