The LT®8315 is a high voltage flyback converter with integrated 630V/300m A switch. No opto-isolator is needed for regulation. The device samples the output voltage from the isolated flyback waveform appearing across a third winding on the transformer. Quasi-resonant boundary mode operation improves load regulation, reduces transformer size and maintains high efficiency.
At start-up, the LT8315 charges its INTVCC capacitor...
