RT3667BT

Dual-Output PWM Controller for AMD SVI2 CPU Power

Supply

General Description

Features

^4/3/2/1-Phase (VDD) + 2/1/0-Phase (VDDNB) PWM

The RT3667BT is a 4 + 2 phases PWM controller, and is

compliant withAMDSVI2 Voltage Regulator Specification

to support both CPU core (VDD) andNorthbridge portion

of the CPU (VDDNB). The RT3667BT features CCRCOT

(Constant Current Ripple Constant On-Time) with the

G-NAVP (Green-Native AVP), which is Richtek's

proprietary topology. TheG-NAVP makes it an easy setting

controller to meet allAMDAVP (Active Voltage Positioning)

VDD/VDDNB requirements. The droop is easily

programmed by setting theDC 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 encoded voltage and current values for the

VDDand VDDNB domains. It can operate in single phase

and diode emulation mode and reach up to 90% efficiency

in different modes according to different loading conditions.

The RT3667BT provides special purpose offset capabilities

by pin setting. The RT3667BT also provides power good

indication, over-current indication (OCP_L) and dual OCP

mechanism for AMD SVI2 CPU core and NB. It also

features fault protection functions, including over-voltage,

under voltage and negative voltage protections.
