I have this question and in the comment i have this texts:
Also, unless your output dampening is excellent, it's usually a bad idea to put unsychnronized SMPS in parallel, unless their datasheet says that's possible. If you need more output current, get a larger inductor, and a switcher IC that can handle more current or one that supports an external MOSFET to handle the current. – Marcus Müller
So i want to know what is the meaning of dampening here :
unless your output dampening is excellent
Thanks.
