VRM8.5 Dual PWM and Dual Linear Power
System Controller
The ISL6523 provides the power control and protection for
four output voltages in high-performance microprocessor
and computer applications. The IC integrates two PWM
controllers and two linear controllers, as well as the
monitoring and protection functions into a 28-pin SOIC
package. One PWM controller regulates the microprocessor
core voltage with a synchronous-rectified buck converter.
The second PWM controller supplies the computer system’s
AGTL+ 1.2V bus power with a standard buck converter. The
linear controllers regulate power for the 1.5V AGP bus and
the 1.8V power for the chipset core voltage and/or cache
memory circuits.
The ISL6523 includes an Intel VRM8.5 compatible, TTL 5-
input digital-to-analog converter (DAC) that adjusts the
microprocessor core-targeted PWM output voltage from
1.050V to 1.825V in 25mV steps. The precision reference
and voltage-mode control provide ± 1% static regulation. The
second PWM controller’s output provides a voltage level of
1.2V with ± 3% accuracy. The linear regulators use external
N-channel MOSFETs or bipolar NPN pass transistors to
provide fixed output voltages of 1.5V ± 3% (V OUT3 ) and 1.8V
± 3% (V OUT4 ).
The ISL6523 monitors all the output voltages. A delayed-
rising VTT (standard buck output) Power Good signal is
issued before the core PWM starts to ramp up. Another
system Power Good signal is issued when the core is within
± 10% of the DAC setting and all other outputs are above
their under- voltage levels. Additional built-in overvoltage
protection for the core output uses the lower MOSFET to
