Hello! For me the main mistery about UC384x IC is design/configuration of external frequency compensation circuit between COMP and FB pins. I can't find good explanation why and in which cases it is necessary, how it affects output of power supply and how to properly design it overall. I wish to find an article with some comparsion examples of waveforms to understand it but no luck. I would be grateful for any articles with detailed explanations. Thank you!
