Advanced PWM and Dual Linear Power Control
The HIP6018B provides the power control and protection for
three output voltages in high-performance microprocessor
and computer applications. The IC integrates a PWM
controllers, a linear regulator and a linear controller as well
as the monitoring and protection functions into a single
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
circuit.
The HIP6018B 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 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 HIP6018B 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)
,
eliminating the need for a current sensing resistor.
