IRU3011

5-BIT PROGRAMMABLE SYNCHRONOUS BUCK

CONTROLLER IC

FEATURES

DESCRIPTION

The IRU3011 controller IC is specifically designed to meet

Dual Layout compatible with HIP6004A

Designed to meet Intel specification of VRM8.4 for Intel specification for latest Pentium IIIä microproces-

Pentium IIIä sor applications as well as the next generation P6 fam-

On-Board DAC programs the output voltage from ily processors. These products feature a patented topol-

1.3V to 3.5V. The IRU3011 remains on for VID code ogy that in combination with a few external components

of (11111).

Loss-less Short Circuit Protection

as shown in the typical application circuit,will provide in

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

Synchronous operation allows maximum efficiency converter while automatically providing the right output

Patented architecture allows fixed frequency

operation as well as 100% duty cycle during

dynamic load

Over-Voltage Protection Output

Soft-Start

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

features, loss less current sensing by using the RDS(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

High current totem pole driver for direct driving of the ±10% window and an Over-Voltage Protection output.

external power MOSFET

Power Good Function

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.

APPLICATIONS

Pentium III & Pentium IIä processor DC to DC

converter application

Low Cost Pentium with AGP
