AIC1573 Datasheet | Analog Intergrations Corporation

5-bit DAC, Synchronous PWM Power Regulator with Simple PWM Power Regulator, LDO And Linear Controller n Features l l n DESCRIPTION The AIC1573 bines two PWM voltage mode controllers and two linear controllers as well as the monitoring and protection functions in this chip. One PWM controller regulates the microprocessor core voltage with a synchronous rectified buck converter. The second PWM controller provides AGP bus 1.5V or 3.3V power with a standard buck converter. Two linear controllers regulate power for the 1.5V GTL bus and 1.8V power for the chip set core voltage and/or cache memory circuits. An integrated 5 bit D/A converter that adjusts the microprocessor core...
