Advanced PWM and Triple Linear Power

Controller

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

(DAC) that adjusts the core PWM output voltage from 1.3V

to 2.05V

0.1V increments. The precision reference and voltage-mode

control provide ±1% static regulation. The AGP bus power

linear controller’s output (V

TTL-compatible signal applied at the SELECT pin, for levels of

1.5V or 3.3V with ±3% accuracy. Based on the status of the

FIX pin, the other two linear regulators provide either fixed

output voltages of 1.5V±3% (V

or user-adjustable by means of an external resistor divider. All

linear controllers can employ either N-channel MOSFETs or

bipolar NPNs for the pass transistor.

The HIP6021 monitors all the output voltages. A single Power

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

voltages above 115% of the DAC setting. The PWM

controller’s over-current function monitors the output current

by using the voltage drop across the upper MOSFET’s
