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.

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.
