SY8401 Datasheet (Silergy) - 0.8A Asynchronous Step Down Regulator

SY8401, 0.8A Asynchronous Step Down Regulator

The SY8401 develops a high efficiency asynchronous step down DC/DC regulator capable of delivering 0.8A output current.

The IC adopts current mode adaptive constant off time control.

The SY8401 operates over a wide input voltage range from 4.5V to 55V and integrates main switch with very low RDS(ON
