25 A Stackable Synchronous Buck Regulator NCP3294 The NCP3294 is a highly efficient stackable synchronous buck regulator, capable of operating with an input range from 3 V to 18 V and supporting up to 25 A continuous load currents. Higher output currents can be achieved by 2 parallel NCP3294 devices operating as an interleaved two phase buck regulator. The NCP3294 utilizes fixed frequency current mode control to provide accurate voltage regulation and fast transient respo.
