FAN5032

8-Bit Programmable 2 to 4 Phase Synchronous Buck

Controller

Features

Description

■ Selectable 2, 3, or 4 phase operation at up to 1MHz

The FAN5032 is a controller for a multi-phase buck

switching regulator optimized to convert a 12V input

supply to the processor core voltage required by high-

performance Intel processors. It has an internal 8-bit

digital to analog converter (DAC) that converts a digital

voltage identiﬁcation (VID) code, sent from the processor

to set the output voltage between 0.5V and 1.6V in

6.25mV steps. It outputs a pulse-width modulated (PWM)

signal to external MOSFET drivers that, in turn, drive the

switching power MOSFETs. The switching frequency of

the design is programmable by a single resistor value

and the number of phases can be programmed to sup-

port 2, 3, or 4 phase applications.

per phase

■ ±7.7mV worst-case differential sensing error over

temperature

■ Active current balancing between the output phases

■ Power good and crowbar blanking supports on-the-ﬂy

VID code changes

■ 0.5V to 1.6V output

■ Fully compliant to Intel VR10 and VR11

speciﬁcations

■ Selectable VR10 extended (7 bit) and VR11 (8 bit)

VID tables

■ Programmable soft-start ramp

The FAN5032 also includes programmable no-load off-

set and droop functions to adjust the output voltage as a

function of the load current, as required by the Intel spec-

iﬁcations. The FAN5032 also provides an accurate and

reliable short-circuit protection function with an adjust-

able over-current set point.

■ Programmable short-circuit protection and latch-off

delay

Special Features

■ 300mV OVP and crowbar threshold

The FAN5032 is speciﬁed over the commercial tempera-

ture range of 0°C to 85°C and is available in a 40-lead

MLP package.

Applications

■ Desktop PC/server processor power supplies for

existing and next-generation Intel processors

■ VRM modules
