Application Notes

  • Fly-Buck(TM) converter provides EMC and isolation in PLC applications

  • AN-2292 Designing an Isolated Buck (Fly-Buck) Converter (Rev. C)
    PDF, 870 Kb, Revision: C, File published: Dec 17, 2014
    In many applications, one or more low-cost, simple to use, isolated power supplies working from input voltages up to 100 V are needed. Traditional solutions use flyback converters to generate this bias supply. Flyback designs typically utilize asymmetric transformers turns ratios for primary and secondary power windings, with an optocoupler and reference, or an auxiliary winding for feedback regul
