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. Richtek's proprietary G-NAVP<sup>TM</sup> (Green Native AVP) makes AVP (Active Voltage Positioning) design easier and more robust. By utilizing the G-NAVP<sup>TM</sup> topology, DEM and CCM efficiency can be improved. The RT8167A integrates high accuracy ADC for platform setting functions, such as no-load offset or over current level. Individual VR ready output signals are provided for both CORE VR and GFX VR. The IC also features complete fault protection functions, including over voltage, under voltage, negative voltage, over current and under voltage lockout. The RT8167A is available in a WQFN-48L 6x6 small foot print package.
