NCP81105, NCP81105H DrMOS Supporting, 1/2/3 Phase Power Controller with SVID Interface for Desktop and Notebook VR12.5 & VR12.6 CPU Applications The NCP81105 is a DrMOS supporting controller optimized for Intel® VR12.5 & VR12.6 compatible CPUs. The controller combines true differential voltage sensing, differential inductor DCR current sensing, input voltage feed−forward, and adaptive voltage positioning to provide accurately regulated power for both Desktop and Notebook CPU applications. The control system is based on Dual−Edge pulse−width modulation (PWM), to provide the fastest initial response to dynamic load events plus reduced system cost. The NCP81105 is compatible with DrMOS type power stages such as NCP5367, NCP5368, NCP5369 and NCP5338.
