TPS54061 datasheet possible typo

I think you have inquired about this directly. Can you provide your calculations? Since you have already done them, I won't have to duplicate it.

here is definitely something off here. Let me see if I can locate the author.

John, Here is spreadsheet of the calculations. Please help answer the following  for customer. They have been waiting and holding their development on confirmation from you  or factory on this.  Revising data sheet is not their  concern at this time. They just need to confirm data sheet parameter if correct or not. See Below. 

: In the TPS54061 datasheet, page 25, Equation 32 and 33, I do not get your ILRMS and ICORMS numbers of 0.1078A and 0.0774A respectively.  Instead, I calculated 0.113A and 0.106A.  Are these equations correct?

Also, in Equation 36 to calculate Co3, what is fco?   Is it the crossover frequency of the output capacitor?  Are you referring to the resonant freq.?

I built a Mathcad file for this already. I do not get the same results either. I am trying to locate the original author to verify what is going on.

Fco is typically closed loop crossover. Flc would be the LC resonant frequency.

Ok. Please let us find out and confirm this info ASAP. Thanks.
