Advanced PWM and Dual Linear Power
Control
The HIP6017 provides the power control and protection for
three output voltages in high-performance microprocessor
and computer applications. The IC integrates a PWM
controller, a linear regulator and a linear controller as well as
the monitoring and protection functions into a single 28 lead
SOIC package. The PWM controller regulates the
microprocessor core voltage with a synchronous-rectified
buck converter. The linear controller regulates power for the
GTL bus and the linear regulator provides power for the
clock driver circuits.
The HIP6017 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 linear regulator uses an internal pass device
to provide 2.5V
±2.5%.
The linear controller drives an
external N-Channel MOSFET to provide 1.5V
±2.5%.
The HIP6017 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 over-
current function monitors the output current by using the
voltage drop across the upper MOSFET’s r
DS(ON)
, thus
eliminating the need for a current sensing resistor.
