Overview

® RT8877D Dual-Output PWM Controller for AMD SVI2 CPU Power Supply General Description The RT8877D is a 4 + 2 phases PWM controller, and is compliant with AMD SVI2 Voltage Regulator Specification to support both CPU core (VDD) and Northbridge portion of the CPU (VDDNB).
The RT8877D features CCRCOT (Constant Current Ripple Constant On-Time) with the G-NAVP (Green-Native AVP), which is Richtek's proprietary topology.
The G-NAVP makes it an easy setting controller to meet all AMDAVP (Active Voltage Positioning) VDD/VDDNB requirements.
The droop is easily programmed by setting the DC gain of the error amplifier.
With proper compensation, the load transient response can achieve optimized AVP pe...
