    An isolated bias supply is implemented in this evaluation board with LM34925 Constant-On-Timeregulator. The LM34925 regulator integrates both the high and low side power switches essential forcreating isolated buck converter.The following include the board specifications:Input Range: 20V to 100VPrimary Output Voltage: 10VSecondary (Isolated) Output Voltage:

    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
