Linear Technology’s 560 VIN micropower no-opto isolated flyback converter with 630 V / 300 mA switch Linear Tech’s LT8315 high voltage flyback converter with integrated 630 V / 300 mA switch needs no opto-isolator for regulation. It samples the output voltage from the isolated flyback waveform appearing across a third winding on the transformer. Its quasi-resonant boundary […]

The LT8315 is a high voltage monolithic flyback regulator that simplifies the design of an isolated DC/DC converter. By sampling the reflected isolated output voltage across the third winding on the power transformer, the part requires no opto-isolator or LT1431 for regulation. The LT8315 operates over an 18V to 560V input voltage range, has a […]
