Description
The RT8859M is a VR12/IMVP7 compliant CPU power controller which includes two voltage rails : a 4/3/2/1 phase synchronous buck controller, the CORE VR, and a single phase buck controller, the AXG VR.
Features
- a quick response mechanism for optimized AVP performance during load transient. The RT8859M supports mode transition function with various operating states. A serial VID (SVID) interface is built in the RT8859M to communicate with Intel VR12/IMVP7 compliant CPU. The RT8859M 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 RT8859M varies with VID, load and input voltage to further enhance the.
