SY8104I Synchronous Step Down Regulator

The SY8104I is a high efficiency 500kHz synchronous step-down DC/DC regulator, which is capable of delivering up to 4A load current. It can operate over a wide input voltage range from 4.2V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss..

SY8104I Features

* Low RDS(ON) for Internal Switches (Top/Bottom): 55mΩ/36mΩ

* 4.2-18V Input Voltage Range

* 4A Output Current Capability

* 500kHz Switching Frequency Minimize the External Components

* Stable with 22µF COUT and 0.68µH Inductor

* Instant PWM Architecture to Achieve Fast Transi
