NEVB-NEX80806DA Evaluation board
The Nexperia NEVB-NEX80806DA board is a reference design of a multimode flyback converter. It enables testing of the functionality and performance of the NEX80806 flyback converter. By simple re-work, the user can add NEX81811 (synchronous rectifier controller) and N-channel power MOSFET to evaluate synchronous flyback converter as well. The 1-layer PCB layout enables easy adaption of this board into a real industrial application of auxilliary power supply.
