DESCRIPTION

The US3007 controller IC is specifically designed to meet Intel specification for Pentium IIä microprocessor applications as well as the next generation of P6 family processors.

FEATURES

■ Provides Single Chip Solution for Vcore,

GTL+ ,Clock Supply & 3.3V Switcher on board

■ Second Switcher Provides Simple Control for

the On board 3.3V supply

■ 200 mA On board LDO regulator

■ Designed to meet Intel VRM 8.2 and 8.3

specification for Pentium IIä

■ On board DAC programs the output voltage

from 1.3V to 3.5V

■ Linear regulator controller on board for 1.5V

GTL+ supply

■ 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

■ Minimum part count

■ 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 Outputs

and generates a Fault output

■ Thermal Shutdown

APPLICATIONS

■ Total Power Soloution for Pentium II processor
