DIY Buck Converter || How to step down DC voltage efficiently
Why people recommend it
GreatScott builds a DIY buck converter with an Arduino driving a MOSFET, cited as a clear way to understand how step-down switching converters work.
Watch for: The slow Arduino feedback loop may regulate poorly at light loads.
