RT8878A Datasheet Dual-Output PWM Controller

Manufacturer: Richtek

Overview: ® RT8878A Dual-Output PWM Controller with 2 Integrated Drivers for AMD SVI2 CPU Power Supply.

General Description

The RT8878A 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 RT8878A

Key Features

  • CCRCOT (Constant Current Ripple Constant On-Time) with G-NAVP (Green-Native AVP), which is 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 error amplifier. With proper compensation, the load transient response can achieve optimized AVP performance. The controller also uses the interface to issue VOTF Complete and to send digitally encod.
