I am looking at a buck switching regulator, but the inductor for it is very large in expensive. The price suddenly goes up.
However if I go for half the current rating of inductor, but I am only using it for a on time of 25%, can I use the inductor?
Will the core reach saturation before then and limit the current (or is this only for transformers)?
Is the only risk burning out the wire like a motor?
Thanks for any help
