RT9227A Datasheet | Richtek

Preliminary Advanced PWM and Dual Fixed Linear Power Controller General Description The RT9227A is a 3-in-one power controller optimized for high-performance microprocessor and puter applications. The IC integrates a synchronous buck PWM controller, a linear regulator and a linear controller as well as monitoring and protection functions into a 24-pin SOP package. The PWM controller regulates the microprocessor core voltage. The linear regulator provides power for the clock driver circuit and the linear controller regulates power for the GTL bus. The RT9227A Features an Intel-patible, TTL 5-bit programmable DAC that adjusts the core voltage from 2.1V to 3.5V in 0.1V...
