DESCRIPTION

The US3010 family of controller ICs are specifically designed to meet Intel specification for Pentium IIä and Pentium Proä microprocessor applications as well as the next generation P6 family processors. These products feature a patented topology that in combination with a few external components as shown in the typical application circuit ,will provide in excess of 16A of output current for an on- board DC/DC converter while automatically providing the right output voltage via the 5 bit internal DAC .

FEATURES

■ Dual Layout Compatible with SC1152

■ Designed to meet Intel specification of VRM8.2 & VRM8.3 for Pentium IIä

■ On board DAC programs the output voltage from 1.3V to 3.5V (US3010) & 1.8V to 3.5V for US3010A

■ 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

■ Over Voltage Protection Output

■ Soft Start

■ High current totem pole driver for direct driving of the external Power MOSFET

■ Power Good function

APPLICATIONS

■ Pentium II & Pentium Proä processor DC to DC converter application

■ Low cost Pentium with AGP
