RT8877C, Dual-Output PWM Controller

® RT8877C Dual-Output PWM Controller for AMD SVI2 CPU Power Supply General .
The RT8877C is a 4 + 2 phases PWM controller.

Features

* CCRCOT (Constant Current Ripple Constant OnTime) with G-NAVP (Green-Native AVP), which is a Richtek's proprietary topology. G-NAVP makes it an easy setting controller to meet all AMD AVP (Active Voltage Positioning) VDD/VDDNB requirements. The droop is easily programmed by setting the DC gain of the
