FEATURES
DESCRIPTION
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 200mA On-Board LDO Regulator Designed to meet Intel VRM 8.2 and 8.3 specification for Pentium II™ 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 drivers for directly driving the external Power MOSFETs Power Good function monitors all outputs Over-Voltage Protection circuitry protects the switcher outputs and generates a fault output Thermal Shutdown It also contains a switching controller to convert 5V to 3.3V regulator for on-board applications that uses either AT type power supply or is desired not to rely on the ATX power supply’s 3.3V output.
