RT3663BH  
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 RT3663BH 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 RT3663BH 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  
RT3663BH provides special purpose offset capabilities by  
pin setting. The RT3663BH 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.
