Beschreibung

The NCP3286, a highly−efficient stackable synchronous buckregulator with PMBus interface, is capable of operating with an inputrange from 3 V to 18 V and supporting up to 40 A continuous loadcurrents. Higher output currents can be achieved by 2, 3, or 4 parallelNCP3286 devices operating as an interleaved multi−phase buckregulator.The NCP3286 utilizes fixed−frequency current−mode control toprovide accurate voltage regulation and fast transient response.Flexible programming of function and parameters supports multipleapplications.
