Many of the newer parts eliminate the need for an opto and TL431. You should consider something like the MAX17690, ADP1071, or ADP1074 to make your life easier!
Very good and understandable explained ! If you want to make a lab power supply then you also have to introduce a op amp for current sensing does that mean that you have then two different compensations which adjust the feedback line ?
Thank you. The short answer is that it does mean that you have two control loops. Parts that include a constant-current loop are usually compensated with one set of components. The LT3790 is one example. (FB and CTRL have separate amplifiers, with the amplifier outputs connected together at the VC pin.) Alternatively, the LT3840 gives you a separate pin (ICOMP) to compensate the part in constant-current. I hope this helps.
One can make his life harder than it can be ! I wanted to go with the UC3842 first but your answer is clearly the easier way to go. That helps thank you very much sir 😃

Excellent. The best by far
Great video, thanks! Would be great if you did an isolated flyback (or whatever topology) that includes a TL431 and opto.

So true. Glad to help.
Hope you attach your files used in the demonstration it helps ,thanks for your effort any way, appreciate
Amazing quality content.
Thank you.
Where we can download that simulation?
Great video. Thank you
Awesome.
Thank you!
Tq..you got a sub
