NCP6133

NCP6133 Advance Information Dual Output 1/2/3 Phase +1/0 Phase Controller with Single SVID Interface for Desktop and Notebook CPU Applications The NCP6133 dual output 1/2/3 phase plus 1/0 buck solution is optimized for Intel 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 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. Dual high performance operational error amplifiers are provided to simplify compensation of the system. Patented Dynamic Reference Injection further simplifies loop compensation by eliminating the need to compromise between closed−loop transient response and Dynamic VID performance. Patented Total Current Summing provides highly accurate current monitoring for droop and digital current monitoring. http://onsemi.com MARKING DIAGRAM 1 52 QFN52 CASE 485BE NCP6133 AWLYYWWG A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week G = Pb−Free Package ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section o...
