General Description

The RT9222 integrates a PWM controller and two low-dropout linear regulators into a single chip.

The PWM controller provides the CPU core voltage controlled by a 5-bit DAC and the linear section regulates power for GTL bus, clock driver or other circuits on motherboards.

The PWM controller provides an adjustable Intel-patible 1.3V~3.5V output voltage.
