I have a general question about a boost converter. I am following the components recommended by the manufacturer. However, the recommended coil package is large and I was looking for a smaller alternative. The alternatives that I found, have different characteristics in resistance and resonance frequency.
a) If the DC resistance of the coil is greater, what are the implications?
b) If the resonant frequency is lower than the recommended component, but still higher than the operating frequency of boost converter, is there a problem? I don't think so, but I would like to hear an opinion.
