Description

The NCP402045 integrates a MOSFET driver, high−side MOSFET

and low−side MOSFET into a single package.

The driver and MOSFETs have been optimized for high−current

DC−DC buck power conversion applications. The NCP402045

integrated solution greatly reduces package parasitics and board space

compared to a discrete component solution.
