Will this AC-DC converter chip really work with arduino? I am looking for a compact solution to convert some 220V/20amp AC to something edible by our arduinos (like 5V/2amp DC). I would like to plug directly my arduino to the wall. I found many things like some Hi-link (HLK-PM01) chips ... But I also found this one :


LNK564DN - US $0.34 / piece
LNK564DN - US $1.14 / piece


That seems perfect, but unfortunatly, I can not find any tuto or example of use for this, shipping included, really cheap chip.

The datasheet is here.

What do you think about it ?

If you have to ask, don't do it. Mains voltage can be dangerous and should only be done if you know what you are doing and how to be safe. The best choice is to just use pre-built adapters from reputable sources.
