® RT8167A Dual Single-Phase PWM Controller for CPU Core/GFX Power Supply 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. The RT8167A supports VR12/ IMVP7 compatible power management states and VID on-the-fly function. The RT8167A operates in two power management states including DEM in PS2 and Forced-CCM in PS1/PS0.
