LM2592HV Simple Switcher step-down voltage regulator

Does anyone have any experience using this 2 amp voltage regulator?

I am considering buying the fixed 3.3V version.
The "Typical Application" example shows a 33uH inductor (and 1N5824 diode, 680uF and 220uF caps) for the 5V version.
Would the 3.3V version also need a 33uH inductor? I assume the inductor would need to be rated at 2 amps or more.
The "INDUCTOR SELECTION PROCEDURE" section in the datasheet also refers to the 5V version. (over my head anyway)
Any help would be appreciated!

EDIT: Would this inductor work? http://www.digikey.com/product-detail/en/6000-330K-RC/M8622-ND/775161

You have table for proper inductor selection...But, generally you have to know in which current zone your supplies will work and of course in many cases that in not known. Take 33uH as producer suggest and it will be ok, but take care about current rating of inductor.
