Need a cheap efficient variable voltage power supply for some project?

Don't want to solder any fiddly parts?

But there are still things that an LM317 will do that this PCB won't... Such as current regulator.

That linked item is quite expensive once you factor in shipping. Quite a few eBay and AliExpress sellers that sell for quite a bit less (delivered).

Switching speed is only 150kHz - only 2/3 aliased side-bands down from within the audible spectrum, and, hence, depending on ripple and regulation quality, I'll be sticking with the 317's for audio, but interesting regardless.
