There are a lot of step down power converter modules (identified as KIS-3R33) around on the internet using the MP2307 buck converter chip, usually advertised as used, taken from a machine. I was thinking of getting a couple to make a lab psu out of instead of a linear regulator.
Does anybody know what they are actually taken from? There must be 1000's available from various sources.
