Description

The FAN5031 device is a multi-phase buck switching

regulator controller, that is optimized to convert a 12V

input supply to the processor core voltage required by

high performance Intel processors. It has an internal 8-bit

DAC that converts a digital voltage identiﬁcation (VID)

code, that is sent from the processor, to set the output

voltage between 0.5V and 1.6V in 6.25 mV steps. It out-

puts a PWM signals to external MOSFET drivers that, in

turn, drive the switching power MOSFETs. The switching

frequency of the design is easily programmable by a

single resistor value and the number of phases can be

programmed to support 2, 3, or 4 phase applications.

The FAN5031 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 FAN5031 also provides an accurate and

reliable short circuit protection function with an adjust-

able over current set-point.

The FAN5031 is speciﬁed over the commercial tempera-

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

MLP package.
