I have a Cosel DC-DC converter. It's pretty straightforward, 2 inputs and 2 outputs. It is an isolated converter, and I was thinking it would probably be best if I put a ground plane beneath it on the PCB, but which side should I ground connect the ground plane to? The input ground or the output ground?
Or would there be two ground planes half on the output side connected to the output ground and half on the input side connected to the input ground? Could something happen if the ground plane gets too close to the ground that it is not connected to?
EDIT: JUst noticed there is a case pin and the manual connects it to the input ground for shielding. I assume I would connect a ground plane to the input ground then to complement the case shield? I am still not sure how to pick the ground to connect it to though.
