Hi, in the application report, "https://www.ti.com/lit/an/slaa287a/slaa287a.pdf", on page 5, a formula for the inductor(L') is mentioned.

After substituting the values, I am getting the value of L' to be 30.83micro Henry, but in the report the value of the inductor used is different. What is the error from my end or is there a fault in the formula provided in the report?
