5 BIT PROGRAMMABLE SYNCHRONOUS BUCK

CONTROLLER IC

PRELIMINARY DATASHEET

FEATURES

DESCRIPTION

Dual Layout Compatible with SC1152

The US3010 family of controller ICs are specifically de-

Designed to meet Intel specification of VRM8.2 signed to meet Intel specification for Pentium IIä and

& VRM8.3 for Pentium IIä Pentium Proä microprocessor applications as well as

On board DAC programs the output voltage the next generation P6 family processors. These prod-

from 1.3V to 3.5V (US3010) & 1.8V to 3.5V for ucts feature a patented topology that in combination

US3010A

Loss less Short Circuit Protection

with a few external components as shown in the typical

application circuit ,will provide in excess of 16A of out-

Synchronous operation allows maximum effi- put current for an on- board DC/DC converter while auto-

ciency matically providing the right output voltage via the 5 bit

Patented architecture allows fixed frequency internal DAC .These devices also feature, loss less cur-

operation as well as 100% duty cycle during rent sensing by using the Rds-on of the high side

dynamic load

Over Voltage Protection Output

Soft Start

Power MOSFET as the sensing resistor, a Power Good

window comparator that switches its open collector out-

put low when the output is outside of a ±10% window

High current totem pole driver for direct driv- and an OVP output. Other features of the device are ;

ing of the external Power MOSFET

Power Good function

Undervoltage lockout for both 5V and 12V supplies , an

external programmable soft start function as well as pro-

gramming the oscillator frequency by using an external

capacitor.

APPLICATIONS

Pentium II & Pentium Proä processor DC to DC

converter application

Low cost Pentium with AGP
