NCP302040
Integrated Driver
and MOSFET
Description
The NCP302040 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 NCP302040
integrated solution greatly reduces package parasitics and board space
compared to a discrete component solution.
