Hello again,
Ok good, if you went over the calculations and got something similar then it should be ok. The larger inductor value will mean lower ripple and less strain on the output cap too. With only 70ma output it's not hard to find a 680uH inductor, but at 70 amps it's an entirely different story. I was trying to find one that would work with a 40 amp converter today and they sure are expensive when you get that high up in current level.
Buck converters like this work with a fairly wide range of inductances anyway, although the design guides like to make it sound critical![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
