Overview

® RT8878B Dual-Output PWM Controller with 2 Integrated Drivers for AMD SVI2 CPU Power Supply General Description The RT8878B 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 RT8878B features CCRCOT (Constant Current Ripple Constant On-Time) with the GNAVP (Green-Native AVP), which is Richtek's proprietary topology.
The 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 error amplifier.
With proper compensation, the load transient response c...
