I have flyback topology for utility meter. I use LNK362GN and TL431 for switching and feedback. In your application notes and PI expert, I have noticed that feedback point is before inductor or ferrite bead. What would be happened if I select feedback point after the inductor? I mean, as seen in the attachment, what would be happened if I select the feedback point 'B' instead of 'A'?
