Hi Team,
As I notice on datasheet figure 5, Typical Application Circuit, the Vline is 85-270Vac. From customer requirements, if Vline ranges from 70-280Vac, can the Vff go beyond 4.7V? Or in this case how could customer adjust to use? Customer set 70Vin to VFF=1.4V, while Vin=280V, VFF=5.6V, is there any influence for VFF beyond 4.7V?
Best Regards,
Gene
