[Noisebridge-discuss] DC-DC Power conversion - Cheapish finds!

[Anders Nelson]

Hey all,

I found some awesome DC-DC non-isolated convertors on Digikey, perhaps you
can benefit from my toils in their search fields. They are all really
compact and handle a buttload of current. Input and output voltage ranges
vary, but these were the cheapest and most available units I found.

You may ask "Why would I pay ten bucks for a switching convertor when I can
pay fifty cents for an LDO?" The answer is heat dissipation and efficiency.
If you don't want to burn people/things and/or literally reduce your
battery life by half (in the case of 12v -> 6v conversion), you should use
a switcher.

And here are some enclosures sized well to protect them:

You can, of course, build your own DC-DC convertor much cheaper. But when
you haven't the time these can save your potato.
