LM3481-Q1: Application Report SNVA761A issues

Part Number: LM3481-Q1

Hi team,

This is Chloe, NWC AA2 FAE. There is an issue about small signal model derived. Such as Figure 6, write the KCL equation according to the last sequence of small signal circuits, and compare formula 14 to get the relationship: Nsp*I=Vout/RLd. But I think the right is Nsp*I*(1-D)=Vout/RLd. So I want to confirm if there are some issues?

...

Thanks for your support!

Best Regards,
