ISL6524A  
FN9064  
Rev 1.00  
Apr 8, 2005  
VRM8.5 PWM and Triple Linear Power System Controller  
The ISL6524A 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 chipset core voltage and/or  
cache memory circuits.  
Features  
• Provides 4 Regulated Voltages  
- Microprocessor Core, AGTL+ Bus, AGP Bus Power,  
and North/South Bridge Core  
• Drives N-Channel MOSFETs  
• Linear Regulator Drives Compatible with both MOSFET  
and Bipolar Series Pass Transistors  
• Simple Single-Loop Control Design  
- Voltage-Mode PWM Control  
• Fast PWM Converter Transient Response  
- High-Bandwidth Error Amplifier  
- Full 0% to 100% Duty Ratio  
The ISL6524A 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%  
• Excellent Output Voltage Regulation  
- Core PWM Output: 1% Over Temperature  
- All Other Outputs: 3% Over Temperature  
• VRM8.5 TTL-Compatible 5-Bit DAC Microprocessor Core

- Wide Range - 1.050V to 1.825V  
The ISL6524A monitors all the output voltages. A delayed-

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 over-voltage protection for  
the core output uses the lower MOSFET to prevent output  
voltages above 115% of the DAC setting. The PWM
