The one above is an LM3886 one side pcb design.

Except for the LM4780, which is more tricky, you can adapt any double side pcb design for 3886 and 3875 and converti into single side. Parts are just a few.

Follow what Kostas changed since his first design to see how it's done.

For the LM3875...

Click the image to open in full size.

I have LM3886 layouts as well, just not handy.

It's all in the datasheet... ROut is optional (useful if you try to parallel these).
