I am quite new to switching power supply design. I found in the recommended application diagram of MAX series there is one 100uH inductor. I wonder there is any requirement about this component. My current consideration is: big enough current, low loss (high efficiency), high frequency (how high? several MHz?).
If I have to homebrew it, what should I do? Such as, how many turns on Amidon FT-50-47 toroid? Thank you for your help!
