NCP6153

NCP6153 Dual Output 3/4 Phase +1/0 Phase Controller with Single SVID Interface for Desktop and Notebook CPU Applications http://onsemi.com The NCP6153 dual output four plus one phase buck solution is optimized for Intel VR12 compatible CPUs. The controller combines MARKING DIAGRAM 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 1 52 QFN−52 CASE 485BE NCP6153 AWLYYWWG 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 A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week G = Pb−Free Package VID performance. Patented Total Current Summing provides highly accurate current monitoring for droop and digital current monitoring.
