SY8263 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. The SY8263 adopts peak current control scheme.
