SY8881 Datasheet (Silergy) - 1A Synchronous Step Down Regulator

SY8881, 1A Synchronous Step Down Regulator

SY8881 is a high efficiency 2.5MHz synchronous step down DC/DC regulator IC capable of delivering up to 1A output currents.

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.
