SY8009 Datasheet (Silergy) - Synchronous Step-Down Regulator

SY8009, Synchronous Step-Down Regulator

The SY8009A and SY8009B are high-efficiency, high frequency synchronous step-down DC-DC regulator ICs capable of delivering up to 1.5A/2A output currents.

The SY8009 family operate over a wide input voltage range from 3V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON)
