The first thing you need to learn when dealing with professional Engineers is good communication. Currently a borderline grade F.
Input voltage 90-270 AC or DC?
Output voltage 88 or 112 AC or DC?
Why can't you make up your mind on output voltage?
What operational current range are you looking at?
What kind of load is it? Inductive, resistive? What?
Why is the input voltage span so wide?
