nn Thermally Enhanced 8-Lead SO Package The LT®8304/LT8304-1 are monolithic micropower isolated flyback converters. By sampling the isolated output
voltage directly from the primary-side flyback waveform,
the parts require no third winding or opto-isolator for
regulation. The output voltage is programmed with two …
