Hi,
For a project I am working on, I need a 90-240VAC to 5V offline converter. The converter would preferably be isolated, with overcurrent protection. Maximum current is 300mA at 5V.
I have bought several ac/dc modules meeting these requirements but the problem is size. I ordered some of these:
https://www.ebay.com/itm/192612896363
These are quite compact, but still larger than my target footprint of less than 0.75 x 0.75x 0.75". Definitely the capacitors are a challenge for keeping the size in this footprint.
What would be the best of all worlds, would be the circuit schematic and magnetics detail of a working circuit so that I can integrate this into my PCB layout and hopefully adjust footprint as needed.
I've done a lot of searching, but micro size doesn't seem available.
Does anyone in the Forum have a source for a small module meeting the size requirements or even better, a circuit design that could be made to fit in this footprint?
Any help, comments or suggestions are welcome and appreciated.
Thanks,
Neko
