SY8263 Overview
Description
The SY8263 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 3A load current. The SY8263 operates over a wide input voltage range from 4.5V to 30V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
