General Description
The RT9238 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 AGTL+ 1.2V bus power. The second linear controller provides power for the 1.5V AGP bus and the 3rd linear controller provides 1.8V power for the chipset core voltage and/or cache memory circuits.
