Published Date: 12/17/2014


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
