SM8103 Datasheet (Silergy) - Synchronous Step Down Regulator

SM8103, Synchronous Step Down Regulator

The SM8103 is a high efficiency, 500kHz synchronous step-down DC/DC regulator capable of delivering up to 3A load current.

It can operate over a wide input voltage range from 4.2V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
