AN-2292 Designing an Isolated Buck (Fly-Buck) Converter (Rev. C)
PDF, 870 Kb, Revision: C, Datei veröffentlicht: 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
