SY8113B Datasheet (Silergy) - Synchronous Step Down Regulator

SY8113B, Synchronous Step Down Regulator

The SY8113B is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of delivering 3A current.

The SY8113B operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
