HIP6028 - Advanced PWM and Dual Linear Power Control with Integrated ACPI Support Interface

Description

This pin is connected to the PWM converter’s output voltage.

The PGOOD and OVP comparator circuits use this signal to report output voltage status and for over voltage protection.

Connect UGATE pin to the PWM converter’s upper MOSFET gate.

Features

HIP6028 Data Sheet May 1998 File Number 4630 Advanced PWM and Dual Linear Power Control with Integrated ACPI Support Interface The HIP6028 provides the power control and protection for three output voltages in high-performance microprocessor and computer applications. The IC integrates a PWM controller, a linear regulator and a linear controller as well as the monitoring and protection functions into a single package. The PWM controller regulates the microprocessor core voltage with a synchronous-rectified buck converter. The linear controller regulates power for the GTL bus and the linear regulator provides power for the clock driver circuit. The HIP6028 includes an Intel-compatible, TTL 5-input digital-to-analog converter (DAC) that adjusts the core PWM output voltage from 2.1VDC to 3.
