LT8303 Datasheet (Linear) - Micropower Isolated Flyback Converter

LT8303, Micropower Isolated Flyback Converter

The LT®8303 is a micropower high voltage isolated flyback converter.

By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no third winding or opto-isolator for regulation.

The output voltage is programmed with a single external resistor.
