uP1664

2-Phase + 1-Phase PWM Controller

with I2C Digital Interface for VR12 CPUs

Features

General Description

The uP1664 is a VR12 compliant CPU voltage regulator

controller supports 2-phase for V_COREand 1-phase for V_GT.

The 2-phase V_COREregulator controller has integrated 12V

MOSFET drivers, and the 1-phase V_GTregulator controller

has a logic level PWM output. This part adopts uPI

proprietary RCOT^TM(Robust Constant On-Time) topology

to have fast transient response and smooth mode

transition. The uP1664 features I2C digital interface. The

integrated I2C interface programmability makes the uP1664

high performance and easy design. Similar to digital based

PWM controller, this device provides many VR parameters

that are programmable by I2C interface to achieve design

flexibility. Platform designer can define different power

scenario for different current states to optimize the VR

performance and efficiency. The uP1664 combines true

differential remote voltage sensing, inductorDCR current

sensing and adaptive voltage positioning to provide

accurately regulated power for desktop CPUs. This device

provides VROK indicator and complete fault protection

functions, including over voltage, under voltage, over current,

and under voltage lockout. The uP1664 is available in

VQFN5X5-40Lpackage.
