3/2/1+2/1-Phase Driver Embedded PWM Controller for IMVP8
uP9507
Features
General Description
The uP9507 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.
Intel IMVP8 Compatible

3+2 Phase: 1 driver for Vcore, 2 drivers for
VccGT
The uP9507 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 uPIs
proprietary RCOT+TM (Robust Constant On-Time) topology
to have fast transient response and smooth mode
transition.

Support Operation Phase Disable Function
Vcore: 3/2/1-Phase
VccGT: 2/1-Phase
Build-in ADC for Platform Parameter Setting
Selectable SVID VR Address
Selectable Vboot Voltage
The uP9507 provides VR_RDY indicator and selectable VR
parameters, such as SVIDVR 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 uP9507 is
available in VQFN7x7 - 60L package.
