General Description
The RT8167A is a dual single-phase synchronous Buck PWM controller with integrated gate drivers, compliant with Intel VR12/IMVP7 specification. A serial VID (SVID) interface is built-in in the RT8167A to communicate with Intel VR12/IMVP7 compliant CPU. The integrated differential remote output voltage sensing function and built-in high accuracy DAC achieve accurate output voltage regulation.
