Any DIMMABLE driver will suffice that can give you up to about 1,000mA of current.
You can, technically, run the XML up to 3,000mA, but in your case, it would be horrendous overkill over a 30cm tank. You'd have to use enough CO2 to make your tank fizz like Mountain Dew to keep algae at bay (ie, don't try it lol).
