RT8807 Overview
The RT8807/A is a two phases synchronous Buck PWM controller with integrated drivers which is optimized for high-performance graphic microprocessor and puter applications. The IC integrates a voltage mode PWM controller, two 5V MOSFET drivers with internal bootstrap diodes, as well as output current monitoring and protection functions into the V/WQFN-24L 4x4 package. The inductor currents are sensed by lossless DCR...
