uP9508

3/2/1+2/1-Phase PWM Controller

with SMBus Digital Interface Control for IMVP8

Features

General Description

Intel IMVP8 Compatible

Support S-Line Desktop CPU

Thermal Sense with VRHOT# Indication

RCOT^+TMControl Topology

The uP9508 is an IMVP8 compliant desktop CPU voltage

regulator controller that integrates a 3-phase PWM

controller for Vcore and a 2-phase PWM 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 outputs

PWM signal to external MOSFET driver to drive the buck

power stage. 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.

Easy Setting

Smooth Mode Transition

Fast Transition Response

External MOSFET Driver Enable Control

Support Operation Phase Disable Function

Vcore: 3/2/1-Phase PWM Outputs

VccGT: 2/1-Phase PWM Outputs

Build-in ADC for Platform Parameter Setting

Selectable SVID VR Address

Selectable SMBus Device Address

Selectable Vboot Voltage

The uP9508 combines true differential output voltage sense,

differential inductor DCR current sense, input voltage

feedforward 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. Similar to digital based PWM controller, the loop

gain is also programmable by SMBus interface to achieve

design flexibility.

System Input Power Monitor P_SYSADC

Enable Control and VR_RDY Indicator

System Thermal Management

Differential Remote Voltage Sense

Differential Current Balance Sense Amplifier

OCP/OVP/UVP/Thermal Shutdown

RoHS Compliant and Halogen Free

The uP9508 provides system input power monitor (PSYS)

ADC, 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 uP9508

is available in VQFN6x6 - 52L package.
