SY8003 1MHz Synchronous Step Down Regulator

The SY8003 and SY8003A are high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to 3A output current. The SY8003 and SY8003A 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.

SY8003 Features

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

* 3A continuous load current capability

* 2.7-5.5V input voltage range

* High switching frequency minimizes the external components: 1MHz

* Internal softstart limits the inrush current

* Reliable short circuit protec
