"switching power supply"

This, IIRC, will go up to 3V and then go down to -3V. With a 1N400X diode in there you can make a pulsed driver, but that's not what you want for a labby :P

You really never know how stable this is with it's pulses and how it'll operate under light load either, but I'd be curious if someone's got one

Nah, it looks like its a switched stepdown converter that puts out proper DC. How stable the output is remains to be seen, i wouldn't risk connecting it directly to a LD.

Actually, no. The "switching" actually refers to the method of voltage regulation used. It is definitely a continuous DC power supply here, so no diode would be needed.

Makes sense... But I'm sure I've seen 'switching' supplies that provide a 'switched' supply... which is no use to us...

Sorry bout that guys :-[
