VRM 8.5 COMPATIBLE

5-BIT PROGRAMMABLE SYNCHRONOUS BUCK

CONTROLLER IC WITH TRIPLE LDO CONTROLLER

DESCRIPTION

FEATURES

Meets Latest VRM 8.5 Specification

The IRU3013 controller IC is specifically designed for

Provides Single Chip Solution for Vcore, 1.2V AGTL+, Intel Pentium III microprocessor applications as de-

scribed in the VRM 8.5 specification. The IC provides

1.8V and VDDQ

On-Board 5-Bit DAC and Decoder programs the out- a single chip solution for the Vcore, 1.2V AGTL+,

put voltage from 1.050V to 1.825V

Loss-less Short Circuit Protection

1.8V and a third uncommitted LDO controller that

can be used either as 1.2V power good detector or

Synchronous operation allows maximum efficiency to provide 1.5V AGP bus in applications that this

Patented architecture allows fixed frequency opera- voltage is required. The IRU3013 features a patented

tion as well as 100% duty cycle when operating with topology that, in combination with a few external com-

a changing load

ponents, (*Note: See application current in figure 3) will

provide in excess of 30A of output current for an on-

board Vcore synchronous converter while automatically

fication. The IRU3013 also features, loss-less current

sensing by using the R^DS(ON)of the high side Power

MOSFET as the sensing resistor, a Power Good win-

dow comparator that switches its open collector output

low when the output is outside of a ±10% window. Other

features of the device are: Under-voltage lockout for both

5V and 12V supplies, an external programmable soft-

start function, and the ability to program the oscillator

frequency by connecting an external capacitor.
