Advanced PWM and Triple Linear Power

Controller

Features

• Provides 4 Regulated Voltages

The HIP6021 provides the power control and protection for

four output voltages in high-performance, graphics intensive

microprocessor and computer applications. The IC integrates

a voltage-mode PWM controller and three linear controllers,

as well as the monitoring and protection functions into a 28-

pin SOIC package. The PWM controller regulates the

microprocessor core voltage with a synchronous-rectified

buck converter. The linear controllers regulate the computer

system’s AGP 1.5V or 3.3V bus power, the 1.5V GTL bus

power, and the 1.8V power for the North/South Bridge core

voltage and/or cache memory circuits. The HIP6021 includes

an Intel-compatible, TTL 5-input digital-to-analog converter

Good signal is issued when the core is within ±10% of the

DAC setting and all other outputs are above their under-

voltage levels. Additional built-in over-voltage protection for

the core output uses the lower MOSFET to prevent output
