NCP303151A中文资料Integrated Driver and MOSFET with IntegratedCurrent Monitor数据手册ONSEMI规格书

描述 Description

The NCP303151 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 NCP303151
integrated solution greatly reduces package parasitics and board space
compared to a discrete component solution.
