Advanced Dual PWM and Dual Linear
Power Control
The HIP6019 provides the power control and protection for four
output voltages in high-performance microprocessor and
computer applications. The IC integrates two PWM controllers,
a linear regulator and a linear controller as well as the
monitoring and protection functions into a single 28 lead SOIC
package. One PWM controller regulates the microprocessor
core voltage with a synchronous-rectified buck converter, while
the second PWM controller supplies the computer’s 3.3V power
with a standard buck converter. The linear controller regulates
power for the GTL bus and the linear regulator provides power
for the clock driver circuits.
The HIP6019 includes an Intel-compatible, TTL 5-input digital-
to-analog converter (DAC) that adjusts the core PWM output
voltage from 2.1V
1.8V
and voltage-mode control provide 1% static regulation. The
second PWM controller is user-adjustable for output levels
between 3.0V and 3.5V with 2% accuracy. The adjustable
linear regulator uses an internal pass device to provide 2.5V
Channel MOSFET to provide 1.5V 2.5%.
The HIP6019 monitors all the output voltages. A single Power
Good signal is issued when the core is within 10% of the DAC
setting and the other levels 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 functions monitor the output current by sensing the
voltage drop across the upper MOSFET’s r
the need for a current sensing resistor.
