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