Well, this is annoying.
I have some little power #modules (bought on #AliExpress, natch) that were advertised as automatic boost/buck converters. Input from <4V to >30V, output from 1.25V to 35V.
They're based on the XL6009 switching converter, which supports auto-buck-boost as one mode.
But they appear to use it in boost-only mode. The output voltage can not go below the input as far as I can tell. From the datasheet, it looks like that's because the auto-buck-boost config requires a few more components, plus a transformer instead of a simple inductor, which is probably the main reason (BOM).
The listing just seems to be ... wrong.
Annoying.

After failing to create a #symmetric #powersupply using an OpAmp and BJTs to split 24V by forming a virtual ground, I went the easy route. Two #BoostConverter set to 12V each are connected in series with the center being ground. This way I get symmetric +/-12V. Of course I don't rely on the #battery protection, but rather use a 900mA #PPTC #fuse per rail. Also a switch and some LEDs as indicator. Enough #JST sockets for my upcoming #synth projects.

Doing a quick test of a boost converter circuit I got on Amazon. I don't think anything will go wrong, but just in case I have the shield.
This is just something quick. I wanted to grab to be able to run a thin client, which needs about 19 volts, from a 12 volt battery. It looks like it should only need a few watts, 10 watts tops from when I was measuring it under load. This is without running a desktop or anything.
