NCP5339 Integrated Driver & MOSFETs The NCP5339 integrates a MOSFET driver, highside MOSFET and lowside MOSFET into a 6 mm x 6 mm 40pin QFN package. The driver and MOSFETs have been optimized for highcurrent www.onsemi.com DCDC buck power conversion applications. The NCP5339 integrated solution greatly reduce package parasitics and board space compared to a discrete component solution.
