HIP6021
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
DC
to 2.05V
DC
in 0.05V steps and from 2.1V
DC
to 3.5V
DC
in
0.1V increments. The precision reference and voltage-mode
control provide
±
1% static regulation. The AGP bus power
linear controller’s output (V
OUT2
) is user-selectable, through a
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
OUT3
) and 1.8V
±
3% (V
OUT4
),
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
r
DS(ON)
.
