Hello everyone, I wanted to build a flyback converter in boundary conduction mode for a constant current LED driver. I wanted to use LT3799 and using 750811291 transformer model. My input voltage is 90-265 Vac, output voltage is 85V, a constant current of 350mA, and output power is around 10-24W. The problem is the datasheet did not mention how to get all the resistance and capacitance values. Only a few values of resistance and capacitance in the datasheet are mentioned. Hope that someone can help me with that.

Hello SIr, I'm thinking of building it on my own as my project.
It is not entirely "on your own", because you ask help.
No guarantee, that answers will accurate.
If you can spend $5.70 (free delivery), you may disassemble it
and will receive full, true information not only about circuit,
but about technology of fabrication such device too.
