Product details

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.
