LT8300 - 100VIN Micropower Isolated Flyback Converter

General Description

The LT®8300 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.
