DESCRIPTION

The US3022 is the first controller IC with five controller in one package specifically designed to meet Intel specification for next generation microprocessor applications requiring multiple on board regulators .

FEATURES

■ Provides Single Chip Solution for Vcore,

GTL+ ,AGP Bus, 1.8V , 2.5V

■ Automatic Voltage Selection for AGP slots

Vddq supply

■ 4 Linear regulator controller on board to

achieve lowest system cost solution

■ Standby Vref provides reference for the ACPI

regulators

■ Designed to meet Intel Latest VRM specification

for next generation micrprocessors

■ On board DAC programs the output voltage

from 1.3V to 2.05V

■ On board resistor dividers provides lowest

component count

■ Loss less Short Circuit Protection for all

outputs

■ Synchronous operation allows maximum

efficiency

■ Patented architecture allows fixed frequency

operation as well as 100 duty cycle during

dynamic load

■ Soft Start

■ High current totem pole driver for direct

driving of the external Power MOSFET

■ Power Good function Monitors all Outputs

■ OVP Circuitry Protects the Switcher Output

and generates a Fault output

APPLICATIONS
