40 A Stackable Synchronous Buck Regulator NCP3296 The NCP3296, a highly efficient stackable synchronous buck regulator, is capable of operating with an input range from 3 V to 18 V and supporting up to 40 A continuous load currents.

Higher output currents can be achieved by 2, 3, or 4 parallel NCP3296 devices operating as an interleaved multi phase buck regulator.

The NCP3296 utilizes fixed frequency current mode control to provide accurate voltage regulation and
