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.
Â
a) If the DC resistance of the coil is greater, what are the implications?
Â
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.
Â
Thanks.
