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.
