Description :

NCP6132 Dual Output 3 Phase & 2 Phase Controller with single SVID Interface for Desktop and Notebook CPU Applications The NCP6132 dual output three plus two phase buck solution is optimized for Intel IMVPï7 and VR12 compatible CPUs. The controller combines true differential voltage sensing, differential inductor DCR current sensing, input voltage feedïforward, and adaptive voltage positioning to provide accurately regulated power for both Desktop and Notebook applications. The control system is based on DualïEdge pulseïwidth modulation (PWM) combined with DCR current sensing providing the fastest initial response to dynamic load events and reduced system cost. It also sheds to single phase during light load operation and can auto frequency scale in light load while maintaining excellent transient performance.
