SY8805A 5A Synchronous Step Down Regulator

The SY8805A is a high-efficiency 1 MHz synchronous step-down DC-DC regulator, Current Mode Control IC capable of delivering up to 5A output current. The SY8805A operates over a wide input voltage range from 3V to 5.5V. It integrates main switch and synchronous switch with very low RDS(ON) to minimi.

SY8805A Features

* Low RDS(ON) for internal switches (top/bottom): 35/15 mohm

* 3-5.5V input voltage range

* 1 MHz switching frequency minimizes the external components

* Internal softstart limits the inrush current

* Up to 98% efficiency

* 0.6V reference voltage
