uP9506  
3/2/1+2/1-Phase Driver Embedded PWM Controller  
with SMBus Digital Interface Control for IMVP8  
Features  
General Description  
The uP9506 is an IMVP8 compliant desktop CPU voltage  
regulator controller that integrates a 3-phase PWM  
controller for Vcore and a 2-phase controller for VccGT.  
The Vcore controller can be configured as 3/2/1-phase, and  
the VccGT controller can be configured as 2/1-phase for  
platform power design flexibility. This part integrates 3  
bootstrap diode embedded 12V MOSFET drivers. For the  
typical 3+2-phase application, the 3-phase Vcore controller  
has one embedded MOSFET driver and two PWM outputs.  
The 2-phase VccGT controller has 2 embedded MOSFET  
drivers. The integrated SMBus interface programmability  
makes this part with high performance and easy design.  
Designer can define different power scenario for different  
current states to optimize the performance and efficiency.

Support Operation Phase Disable Function  
The uP9506 combines true differential output voltage sense,  
differential inductorDCR current sense, input voltage feed-  
forward sense and adaptive voltage positioning to provide  
accurately regulated power for desktop CPU. It adopts uPI’s  
proprietary RCOT+TM (Robust Constant On-Time) topology  
to have fast transient response and smooth mode  
transition. Similar to digital based PWM controller, the loop  
gain is also programmable by SMBus interface to achieve  
design flexibility.

Optimization  
The uP9506 provides VR_RDY indicator and selectable VR  
parameters, such as SVID VR address, SMBus device  
address and Vboot voltage. It also provides complete fault  
protection functions, including over voltage, under voltage,  
over current, over temperature and under voltage lockout.  
The uP9506 is available in VQFN7x7 - 60L package.
