NCP81022 Dual Output 4 Phase Plus 1 Phase Digital Controller with SVI2 Interface for Desktop and Notebook CPU Applications www.onsemi.com The NCP81022 dual output four plus one phase buck solution is optimized for AMD® SVI2 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 DCR current sensing providing an ultra fast initial response to dynamic load events and reduced system cost.
