Description

The NCP81391/A 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−boost power conversion applications. The NCP81391/A integrated solution greatly reduces package parasitics and board space compared to a discrete component solution.
