You're right. The current rating for an inductor is an "up to" value, as it states the maximum current you can pass through that part without saturating the ferrite core. A saturated inductor in a boost converter will heat up and the converter won't reach designated voltage. Btw. I've read somewhere, that for boost converters you shouldn't use inductors with "o" shaped core or any closed loop core inductors, as they are much easier to saturate. I've done only very short tests, and it was true - but maybe the peak current of the inductor was too high, I can only measure average, which was 3x lower than that coil max specified current. Can anyone confirm if it is possible or not to use closed loop ferrite cores for converter coils?
