I am designing a SEPIC converter using a LT8364 for "power aplications" and a buck converter using a TPS62125 for powering a MCU.
Since I have a bunch (>100pcs) of 100uF, 16V, electrolitic caps laying around, I would like to use them to store a of bit current at the exit of thesse two switching converters.
I understand that using a big capacitor is better if you have an instant and huge current need, but I do not know what happends when you start everything up.
Question 1: Would a 100uF electrolitic capacitor draw an extremly high current at startup, as all capacitors do when they are being charged up and therefore would it destroy the IC or the inductor or would it be just fine because it's only high current for a fraction of a second?
Question 2: Would it be more effective to use a smaller value ceramic capacitor?
P.S. For the SEPIC, output would never go over 14V.
