General Description
The RT9231 is a 4-in-one power controller optimized for high-performance microprocessor and computer applications. The IC integrates a PWM controller, triple linear controller as well as monitoring and protection functions into a 28-pin SOP package. The PWM controller regulates the microprocessor core voltage with a synchronous buck converter. The first linear controller supplies the computer system’s AGP 1.5V or 3.3V bus power. The second linear controller provides power for the 1.5V GTL bus and the 3rd linear controller provides 1.8V power for the North/South Bridge core voltage and/or cache memory circuits.
