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
