Datasheet	RT9238-Richtek.pdf

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.

an Intel VRM8.5 compatible, TTL 5-bit programmable DAC that adjusts the core voltage from 1.090V to 1.865V in 25mV steps. The 5bit DAC has a typical ±1% tolerance. The linear regulators provide fixed output voltages of 1.2V (VOUT2), 1.5V (VOUT3) and 1.8V (VOUT4) or useradjustable.
