Why does this boost converter circuit not work? Answered
I tried this circuit using a 3.7v supply and instead of a 12v Zener I used a 5v Zener. I also used a 22uH inductor. I get 5v no load but when I add a load the voltage drops a bit and the current is 50ma max. Why is this not working and what could I change to make it work? If this is the wrong circuit altogether, then what discrete circuit would work?
