AIC1571 - 5-bit DAC/ Synchronous PWM Power Regulator with Dual Linear Controllers
The AIC1571 combines 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
