NCP81081 Datasheet | onsemi

NCP81081 Integrated Driver and MOSFET The NCP81081 integrates a MOSFET driver , high- side MOSFET and low - side MOSFET into a 6 mm x 6 mm 40 - pin QFN package. The driver and MOSFET s have been optimized for high- current DC- DC buck power conversion applications. The NCP81081 integrated solution greatly reduces package parasitics and board space pared to a discrete ponent solution. Features http://onsemi.
