LT8300 100VIN Micropower Isolated Flyback Converter with 150V/260m A Switch 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. Internal pensation and soft-start further reduce external ponent count. Boundary mode operation...
