RT3663BM

Dual-Output PWM Controller with 3 Integrated Drivers for

AMD SVI2 Mobile CPU Power Supply

General Description

Features

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

The RT3663BM is a 3 + 2 phases PWM controller, and is

compliant withAMDSVI2 Voltage Regulator Specification

to support both CPU core (VDD) andNorthbridge portion

of the CPU (VDDNB). The RT3663BM features CCRCOT

(Constant Current Ripple Constant On-Time) withG-NAVP

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

topology. TheG-NAVP makes it an easy setting controller

to meet allAMDAVP (Adaptive 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

optimizedAVP performance. The controller also uses the

interface to issue VOTF Complete and to send digitally

encoded voltage and current values for the VDD and

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

RT3663BM provides special purpose offset capabilities

by pin setting. The RT3663BM also provides power good

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

mechanism for AMD SVI2 CPU core and NB. It also

features complete fault protection functions including over-

voltage, under-voltage and negative-voltage protections.
