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 response.

Flexible programming of function and parameters supports multiple

applications.
