FAN5029

8-Bit Programmable 2- to 5-Phase Synchronous Buck Controller

Description

Features

The FAN5029 is

a multi-phase buck switching

• Selectable 2-, 3-, 4-, or 5-phase operation at up to

regulator controller 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. It outputs a PWM 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 support 2-, 3-, 4-, or 5-phase applications.

1MHz per phase

• ±7.7mV worst-case differential sensing error

• Active current balancing between the output phases

• Power good and crowbar blanking supports on-the-

fly VID code changes

• Selectable VR10 extended (7-bit) and VR11 (8-bit)

VID tables

• Programmable short-circuit protection and latch-off

delay

• Programmable soft start ramp

The FAN5029 also includes programmable no-load

offset and droop functions to adjust the output voltage

as a function of the load current, as required by the

Intel specifications. The FAN5029 also provides an

accurate and reliable short-circuit protection function

with an adjustable over-current set point.

Applications

• Desktop PC/Server processor power supplies for

existing and next generation Intel processors

• VRM modules products

The FAN5029 is specified over the extended

commercial temperature range of 0°C to +85°C and is

available in a 40-lead MLP package.

Part Numbers

• FAN5029MPX is not for new designs.

• The FAN5029MPX_NAAC238 replaces the

FAN5029MPX and is compatible with all VR10 and

VR11 processors.
