hi I am using meanwell LDD 700H driver and iam confused on how to ground the output
i ground the input pin but I do not connect the output ground to input ground , should i connect those together?
For -Vin it says, RIGHT THERE ON THE DATA SHEET, , "don't connect to -Vout". I guess that means you shouldn't connect them together. Further, why do you even think you need to "ground the output"? You're driving an LED; connect one side of the LED to +Vout, connect the other side to -Vout. Done.

Upon closer examination, I realize I have no idea what you are trying do. The LDD700 is a constant- current led driver that you have hooked up to some unidentified device, perhaps a regulator? WHAT IS GOING ON HERE?
And what is the output LDD700? It's a constant current. I think you want a DC-DC VOLTAGE converter, not an LED driver. Or, better yet, why don't you just use two switching regulators?
