UCC28710: Reference design PMP10319.

Part Number: UCC28710
Other Parts Discussed in Thread: PMP10319

Hi team,

My customer plan to design with reference to PMP10319.
https://www.tij.co.jp/tool/jp/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)=81.75uH82uH

Sincerely.
Kengo.
