I am hoping someone can help me understand what I am missing on this datasheet for a Linear LT3652 charger.

Trying to layout a test circuit with this chip and the method to calculate the inductor does not appear to match the examples given.

The formula to determine the inductor given in IMG-A.PNG

Values used in the sample schematic

R

_{sense} = .05 (50mOhm) Current sense

I

_{CHG(max)} = 2amps charge current

V

_{bat(flt)} = 8.3v Float voltage

V

_{IN(MAX)} = 12v Max input voltage

IMG-B.PNG is the sample schematic where the inductor is 8.2uH

It also shows the rather miraculous setup where 12 watts goes in and 16.6 watts comes out - it makes power I guess. Convenient for sure

I did not get a number even in the ballpark of 8.2uH - closer to 1. This looks simple, but clearly, I am messing it up.
