The LT
The LT8302 is a monolithic micropower isolated flyback converter designed for applications requiring high efficiency and low component count. It samples the isolated output voltage directly from the primary-side flyback waveform, eliminating the need for a third winding or opto-isolator for regulation. The device features a 3.6A, 65V DMOS power switch integrated with high voltage circuitry and control logic in an 8-lead SO package.
