NCP5369 Integrated Driver and MOSFET The NCP5369 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 NCP5369 integrated solution greatly reduces package parasitics and board space MARKING compared to a discrete component solution.
