RT3667BY  
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 RT3667BY 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 RT3667BY 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 RT3667BY provides special purpose offset capabilities  
by pin setting. The RT3667BY 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.
