General Description

The RT3667BB 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).

Overview

® RT3667BB Dual-Output PWM Controller with 2 Integrated Drivers for AMD SVI2 CPU Power Supply.

Key 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 can achieve optimized AVP performance. The controller also uses the interface to issue VOTF Complete and to send digitall.
