uP1649Q

1/2/3/4-Phase PWM Controller

with SMBus Digital Interface Control for VR12.5

Features

General Description

The uP1649Q is a VR12.5 compliant CPU power controller Intel VR12.5 Compliant

RCOT^TMControl Topology

supports up to 4 phases. The integrated I2C interface

programmability makes the uP1649Q 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 Transient

Fast Transient Response

True Differential Current Balance Sense Amplifier

Differential Remote Voltage Sensing

Build-in ADC for Platform Setting

The uP1649Q combines true differential voltage sensing,

differential inductor DCR current sensing, input voltage

feed-forward and adaptive voltage positioning to provide

accurately regulated power for desktop CPUs. It adopts

uPI 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 I2C interface to achieve

design flexibility.

Programmable Loop Gain

The uP1649Q provides VR_READY indicator. It also

features complete fault protection functions including over

voltage, under voltage, over current, over temperature and

under voltage lockout. The uP1649Q is available in

VQFN5X5 - 40L package.
