SY8105I Synchronous Step Down Regulator

The SY8105I is a high efficiency 500kHz synchronous step-down DC/DC regulator, which is capable of delivering up to 5A load current. It can operate over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

SY8105I Features

* Low RDS(ON) for Internal Switches (Top/Bottom): 41mΩ/27mΩ

* 4.5-18V Input Voltage Range

* 5A Output Current Capability

* 500kHz Switching Frequency Minimize the External Components

* Stable with 22µF COUT and 0.68µH Inductor
