Buck converter coil selection (Coilcraft vs Bourns)
I am using the SCT2331 (a clone of the Diodes AP63200, with 400KHz switching frequency instead of 500KHz). The design works with an inductor from Coilcraft (LPS3314-103), but when I try a different, ...

inductor resistor variance for a buck regulator circuit
Thanks to some very helpful folks in another thread, I've selected a buck regulator for a microprocessor project that draws on automotive current, i.e., reducing 12v to 5v with about 2amps of power. I ...

Why do buck (step-down) switching regulators require an inductor and diode?
So, I understand, at least at a basic level, the method of operation of switching converters, both buck and boost. What puzzles me, though, is why buck converters in particular aren't simpler.
Why ...
