Hi,
I am debugging one AC-DC quick charger from last week. I saw a general feedback circuit using TL431 common in all AC-DC converters.
This is what i found in my board(Please see the figure). I want to know how capacitor C1 works in this Circuit. If we dont give that capacitor C1 then we didnt get the TL431 cathode voltage regulated at 2.5. Whats the role of that capacitor
