General Description

The AIC1571 bines a synchronous voltage mode controller with two linear controllers as well as the monitoring and protection functions in this chip.

The PWM controller regulates the microprocessor core voltage with a synchronous rectified buck converter.

One linear controller regulates power for the GTL bus and the other linear controller provides power for the clock driver circuit or memory (1.8V) An integrated 5 bit D/A converter that adjusts the core PWM output voltage from 2.1V to 3.5V in 0.1V increments and from 1.3V to 2.05V in 0.05V increments.
