The LM5019 evaluation board provides the design engineer with a fully functional buck regulator,employing the constant on-time (COT) operating principle. This evaluation board provides a 10V outputover an input range of 12.5V to 100V. - AN-2292 Designing an Isolated Buck (Fly-Buck) Converter (Rev. C)PDF, 870 Kb, Revisión: C, Archivo publicado: dic 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
