NCP6132ADMNR2G Description
The NCP6132ADMNR2G dual output three plus two-phase buck solution is optimized for Intel IMVP?7 and VR12 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 applications. The control system is based on Dual?Edge pulse?width modulation (PWM) combined with DCRcurrent sensing providing the fastest initial response to dynamic load events and reduced system cost. It also sheds to a single phase during light load operation and can auto frequency scale in light load while maintaining excellent transient performance.
