OPT8241: Guidance request to calculate minimum inductance of high frequency inductor

Jason Work1

Part Number: OPT8241

In application note, SBAA209B, how do you calculate an inductance value of 84 nH? Is this right? It looks like the application note failed to mention that the input voltage is 10 V.

Here is the same calculation using the voltsecond method described in application note SNVA038B.
