UCC28710: Reference design PMP10319.

Hi team,

My customer plan to design with reference to PMP10319.

But, I couldn't find a way to calculate L2 in the below schematic.
Could you tell me about it?

I think this is, is it correct?
　L=(Vout+Vf)/(ΔIL*fsw)=(15V+1.35V)/(2A*100kHz)=81.75uH→82uH

Sincerely.
Kengo.
