HIP6020A
Advanced Dual PWM and Dual Linear
Power Controller
The HIP6020A provides the power control and protection for
four output voltages in high-performance, graphics intensive
microprocessor and computer applications. The IC
integrates two PWM controllers and two linear controllers, as
well as the monitoring and protection functions into a 28-pin
SOIC package. One PWM controller regulates the
microprocessor core voltage with a synchronous-rectified
buck converter. The second PWM controller supplies the
computer system’s AGP 1.5V or 3.3V bus power with a
standard buck converter. The linear controllers regulate
power for the 1.5V GTL bus and the 1.8V power for the
North/South Bridge core voltage and/or cache memory
circuits.
The HIP6020A 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 second PWM controller’s output is user-
selectable, through a TTL-compatible signal applied at the
SELECT pin, for levels of 1.5V (
±
3%) or fully ON switch. The
linear regulators use external N-Channel MOSFETs or
bipolar NPN pass transistors to provide output voltages of
1.5V
±
3% (V
OUT3
) and 1.8V
±
3% (V
OUT4
).
The HIP6020A 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
controllers’ over-current function monitors the output current
by using the voltage drop across the upper MOSFET’s
r
DS(ON)
, eliminating the need for a current sensing resistor.
