This reference design provides 5.2-V, 4-W isolated voltage from 5-V DC-input supply. The isolated output voltage is sampled from the primary-side flyback voltage that eliminates the need for an optocoupler, voltage reference or third winding from the transformer for output voltage regulation. The high level of integration results in a simple, reliable and high-density design with only one component crossing the isolation barrier.
