IRU3018

5-BIT PROGRAMMABLE SYNCHRONOUS BUCK PLUS

LDO CONTROLLER AND 200mA LDO ON-BOARD

FEATURES

DESCRIPTION

Provides single chip solution for Vcore, GTL+ & clock The IRU3018 controller IC is specifically designed to meet

supply

Intel specification for Pentium II microprocessor appli-

cations as well as the next generation of P6 family pro-

200mA On-Board LDO Regulator

Designed to meet the latest Intel specification for cessors. The IRU3018 provides a single chip controller

Pentium II

On-Board DAC programs the output voltage from 200mA regulator for clock supply which are required for

1.3V to 3.5V the Pentium II applications. These devices feature a pat-

IC for the Vcore, LDO controller for GTL+ and an internal

Linear regulator controller on board for 1.5V GTL+ ented topology that in combination with a few external

supply

components as shown in the typical application circuit,

will provide in excess of 18A of output current for an on-

Loss-less Short Circuit Protection with HICCUP

Synchronous operation allows maximum efficiency board DC-DC converter while automatically providing the

patented architecture allows fixed frequency opera- right output voltage via the 5-bit internal DAC. The

tion as well as 100% duty cycle during dynamic IRU3018 also features loss-less current sensing for both

load

switchers by using the R^DS(on)of the high-side power

MOSFET as the sensing resistor, internal current limit-

Soft-Start

High current totem pole driver for direct driving of the ing for the clock supply, and a Power Good window com-

external power MOSFET

parator that switches its open collector output low when

any one of the outputs is outside of a pre-programmed

Power Good Function monitors all outputs

Over-Voltage Protection circuitry protects the window. Other features of the device are: Under-voltage

switcher output and generates a fault signal

Thermal Shutdown

lockout for both 5V and 12V supplies, an external pro-

grammable soft-start function, programming the oscilla-

tor frequency via an external resistor, Over-Voltage Pro-

tection (OVP) circuitry for both switcher outputs and an

internal thermal shutdown.
