onsemi NCP81381
The NCP81381 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 NCP81381 integrated solution greatly reduces package parasitics and board space compared to a discrete component solution.| Part No. | NCP81381 |
