Your name or email address: Apr 1, 1. The whole setup is made on a breadboard, but I’ve tried to keep the relevant connections as short as possible. I had a similar experience when I first got into switching regulators and used an inappropriately sized inductor, which would regulate for small loads and drop to near 0V for large ones, the inductor had fried and seemed to make contact when there wan’t much heat generated in the coil and was open when it heated up.

It would be helpful to see a picture of the coil.
