SY8089 Datasheet (Silergy) - Synchronous Step Down Regulator

SY8089, Synchronous Step Down Regulator

The SY8089 and SY8089A are high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to 2A output current.

The SY8089 and SY8089A operate over a wide input voltage range from 2.7V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) t

SY8089 Features

* Low RDS(ON) for internal switches (top/bottom):110mΩ/80mΩ

* 2.7-5.5V input voltage range

* 2A continuous, 3A peak load current capability

* 1MHz switching frequency minimizes the external components

* Internal softstart limits the inrush current
