No-Opto Isolated Flyback Converters
The no-opto isolated flyback parts from Linear need no opto-coupler or LT1431 shunt regulator for regulation. They sense the isolated output voltage directly from the primary-side waveform. This simplifies the design, allows for a smaller solution size and only requires one component crossing the isolation barrier. The load, line and temp drift is less than ±5%. Several off-the-shelf transformers are shown in the data sheets making it easy to complete the design.
