Could a larger capacitor, at the output of the SMPS, destroy components with larger current draw when its being charged?

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 ...

SMPS voltage ripple

I'm using the MC34063 for my 35 VDC -> 4VDC SMPS. Here is the circuit (modelled in LTSpice): Edit: However, using a MC34063 calculator and setting Ipeak = 0.5A, L1 = 37 uH C3 = 12.5 uF Which, ...

MLCC as SMPS filter caps

This question is out of curiosity. I know fairly well that mains SMPS can suffer from bad electrolytic caps. Now I wonder if replacing all electrolytics with MLCCs work? Will it make a more durable ...
