UCC28070A: Power Limit based on Universal AC Line Vrms

Hello,

I recently reached out to TI and saw that a question was asked on my behalf regarding this issue, but, I can no longer find it..

I was hoping you would be able to help me with a hardware solution, hopefully a feature of the UCC28070A, so that based on a certain AC Vrms the power limit to the user changes. For instance, say at 200 Vrms and above you are able to access full power, and below only half power.

Is this sort of functionality done through Rimo and Imo current setting?

If not, are you able to propose an idea on how this is usually achieved? 

Thanks, Will
