The APW6021 is a high-performance, graphics intensive microprocessor and computer application power control IC from ON Semiconductor. The IC integrates voltage-mode 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 micro-processor core voltage with a synchronous-rectified buck converter. The linear controllers regulate the computer system’s AGP 1.5V or 3.3V bus power, the 1.5V GTL bus power, and the 1.8V power for the North/South Bridge core voltage and/or cache memory circuits. The APW6021 includes an Intel-compatible, TTL 5-input digital-to-analog converter (DAC) that adjusts the core PWM output voltage from 1.3 VDC to 2.05 VDC in 0.05V steps and from 2.1 VDC to 3.5 VDC in 0.1V increments. The precision reference and voltage-mode control provide ±1% static regulation. The AGP bus power linear controller’s output (VOUT2 ) is user-selectable, through a TTL-com- patible signal applied at the SELECT pin, for levels 1.5V or 3.3V.
