Hello everyone, just something that's been bugging me for quite a while now;
How do the tiny dc-dc computer power supplies that usually come with tiny cases actually work whilst being so small?
It's astounding that a board nopt much larger than a standard atx connector (in the case of a Pico PSU) can deliver enough current to drive a board and drives and the likes.
I've built a small atx style supply to run one such board and still can't figure out how they use such small inductors. I understand they're switching supplies, and know roughly how they work, but without a schematic to work from i'm stumped.
Has anyone got any schematics or even block diagrams on how these devices work to deliver not inconsiderable current whilst being small enough to fit in the tightest of spaces?
Any info would be greatly appreciated, i'd quite like to learn how it's done so I can build my own rather than waste a day waiting for the delivery guy to deliver Many thanks
