for my Bachelorthesis I had to edit a flyback converter application and used the LT8304 for control. My example was a demo board with the following circuit:
I had different output values, but I got my board working! I just have three questions for my documentation:
- What is the capacitor 'C9' supposed to do and how it was dimensioned?
- How the values for the Snubber (R3 and C4) were dimensioned?
- How do the resistors 'R4' and 'R6' affect the output voltage? This problem I tried to solve by studying the Block disgram in the LT8304-datasheet, but I can't understand how it works.
Maybe some of you could help me with those questions. I would be very grateful!
