Description
The RT8199B is a VR12.1 compliant CPU power controller which includes one voltage rails : a 1 phase synchronous buck controller, the CORE VR.
Features
- a quick response mechanism for optimized AVP performance during load transient. The RT8199B supports mode transition function with various operating states. A Serial VID (SVID) interface is built in the RT8199B to communicate with Intel VR12.1 compliant CPU. The RT8199B supports VID on-the-fly function with three different slew rates : Fast, Slow and Decay. By utilizing the G-NAVPTM topology, the operating frequency of the RT8199B varies with VID, load and input voltage to further enhance the ef.
