5-BIT PROGRAMMABLE SYNCHRONOUS BUCK

CONTROLLER IC

DESCRIPTION

The IRU3011 controller IC is specifically designed to meet

Intel specification for latest Pentium III鈩?microproces-

sor applications as well as the next generation P6 fam-

ily processors. These products feature a patented topol-

ogy that in combination with a few external components

as shown in the typical application circuit,will provide in

excess of 20A of output current for an on-board DC/DC

converter while automatically providing the right output

voltage via the 5-bit internal DAC. These devices also

features, loss less current sensing by using the R

DS(ON)

of the high side Power MOSFET as the sensing resis-

tor, a Power Good window comparator that switches its

open collector output low when the output is outside of a

鹵10%

window and an Over-Voltage Protection output.

Other features of the device are: Under-voltage lockout

for both 5V and 12V supplies, an external programmable

soft-start function as well as programming the oscillator

frequency by using an external capacitor.

FEATURES

Dual Layout compatible with HIP6004A

Designed to meet Intel specification of VRM8.4 for

Pentium III鈩?/div>

On-Board DAC programs the output voltage from

1.3V to 3.5V. The IRU3011 remains on for VID code

of (11111).

Loss-less Short Circuit Protection

Synchronous operation allows maximum efficiency

Patented architecture allows fixed frequency

operation as well as 100% duty cycle during

dynamic load

Over-Voltage Protection Output

Soft-Start

High current totem pole driver for direct driving of the

external power MOSFET

Power Good Function

APPLICATIONS

Pentium III & Pentium II鈩?processor DC to DC

converter application

Low Cost Pentium with AGP
