Overview
Integrated Driver and MOSFET NCP302045 Description The NCP302045 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 NCP302045 integrated solution greatly reduces package parasitics and board space compared to a discrete component solution.
