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% (V OUT2), 1.5V 3% (VOUT3) and 1.8V 3% (VOUT4). |
