Programmable Point-of-Load Controller with 6-bit VID

Description

Features

The PI1004 IC combines a Voltage Identification Digital

Input (VID) controlled reference with control and

supervisory functions to accurately set the regulator

output voltage at the point of load, for isolated and CPU

DC-DC converters in desktop and server applications. The

PI1004 feature set is intended to be used in conjunction

with a variety of power architectures, including Factorized

Power Architecture (FPA), to provide CPU power in

• 0.5% Typical initial output voltage accuracy

• Remote differential output voltage sense

• 6 Bit DAC, with 12.5 mV resolution

• 5 V to 12 V Operation

• Power good output with blanking

• Programmable adaptive voltage positioning (AVP)

accordance with Intel VR10.X requirements. The feature

• Over voltage protection (OVP) output or

programmable VID offset

set includes a precision error amplifier for remote

differential sensing of the output voltage, a six bit

programmable VID reference voltage output with 12.5

mV resolution, and flexible adaptive voltage positioning.

The regulation voltage can also be shifted below the VID

range with a programmable offset current. The controller

includes an over-voltage indicator output, an open

collector power-good output, under-voltage lockout and

an externally programmable soft start.

• Programmable soft start

• Optimized for VRM/VRD 10.X specifications

• 20 MHz Gain bandwidth amplifier

• Enable input

Applications

• Supports FPA

The PI1004 is available in two options; PI1004-1:

Programmable VID offset current and no OVP output. The

VID offset current is used to create an offset to the DAC

output. PI1004-2: OVP output and no VID offset.

• Intel VR10.X CPU Power

• Workstation CPU Power

• Isolated DC-DC Converters

Package

• 24-Lead (4mm x 4mm) QFN
