Thanks, I appreciate that the inductor value is small, but if you look at the schematic on page 9 of the attached document, it shows a 100nH inductor doing output LC filtering at the output of a 200W SMPS.
I actually ran this on the bench with vin=48vdc and vout=36vdc and 100w load and the ripple voltage upstream of this inductor is 700mV pkpk and just 30mV pkpk downstream of this inductor….which shows that for high frequency SMPS like this, very low inductor values have their merits.
The SMPS of the attached page 9 runs at 1MHz, but the one that we are wanting to filter now, has a 3MHz output ripple frequency, and is a vicor VTM module with vin=36vdc and vout =1v5 and iout=65A.....so i was thinking of a very low henry value inductor.
