HIP6019
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
thesecondPWMcontrollersuppliesthecomputer’s3.3Vpower
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
DC
to 3.5V
DC
in 0.1V increments and from
1.8V
DC
to 2.05V
DC
in 0.05V steps. The precision reference
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
±
2.5%. The adjustable linear controller drives an external N-
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
DS(ON)
, eliminating
the need for a current sensing resistor.
