    An isolated bias supply is implemented in this evaluation board with LM34927 Constant-On-Timeregulator. The LM34927 regulator integrates both the high and low side power switches essential forcreating isolated buck converter.The board specifications are as follows:Input Range: 20 V to 100 VPrimary Output Voltage: 10 VSecondary (Isolated) Output Voltage: 9.5

    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
