I would like to use UCC25600 and referring to UCC25600EVM for my low power LLC design with Vin=12V, Vout=5V, Iout=4A, fr=100kHz. I have completed and verified by simulating my resonant component values. Now, I need to design the feedback through optocoupler. I'm not able to find suitable references for the same. I would appreciate any input for finding the solution.
The section which I am referring to is highlighted in the attached file.
Thanks and regards,
