HIP6019B
Advanced Dual PWM and Dual Linear
Power Control
The HIP6019B 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 HIP6019B includes an Intel-compatible, TTL 5-input
digital-to-analog converter (DAC) that adjusts the core PWM
output voltage from 2.1VDC to 3.5VDC in 0.1V increments
and from 1.3VDC to 2.05VDC 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 HIP6019B 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.
