ISL6524CBZ规格书详情
The ISL6524 provides the power control and protection for
four output voltages in high-performance microprocessor
and computer applications. The IC integrates one PWM
controller and three linear controllers, as well as the
monitoring and protection functions into a 28-pin SOIC
package. The PWM controller regulates the microprocessor
core voltage with a synchronous-rectified buck converter.
One linear controller supplies the computer system’s AGTL+
1.2V bus power. The other two linear controllers regulate
power for the 1.5V AGP bus and the 1.8V power for the chip
set core voltage and/or cache memory circuits.
The ISL6524 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 linear
regulators use external N-channel MOSFETs or bipolar NPN
pass transistors to provide fixed output voltages of 1.2V ±3
(VOUT2), 1.5V ±3 (VOUT3) and 1.8V ±3 (VOUT4).
The ISL6524 monitors all the output voltages. A delayedrising VTT (VOUT2 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 undervoltage levels. Additional built-in overvoltage protection for
the core output uses the lower MOSFET to prevent output
voltages above 115 of the DAC setting. The PWM
controllers’ overcurrent function monitors the output current
by using the voltage drop across the upper MOSFET’s
rDS(ON), eliminating the need for a current sensing resistor.
