Can I power this converter from 5 V?
No. The input range is 2.97 V to 3.63 V, so it is intended for a 3.3 V input rail. Use a 5 V regulator upstream if your source is 5 V.
Does the isolated output share ground with the input?
No. Because the output is isolated, its ground is separate from the input ground. Do not tie the two grounds together unless your design requires it, since that removes the isolation.
