SY8891 Datasheet (Silergy) - 5.5V/1A Synchronous Step Down Regulator

SY8891, 5.5V/1A Synchronous Step Down Regulator

The SY8891 is a high efficiency 1.5MHz synchronous step down DC/DC regulator, capable of delivering up to 1A output current.

It can operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS (ON) to minimize the conduction loss.
