Good Morning All,
I'm wondering if someone could shed some light on something for me? I using a 6562AT Power Factor Controller for an offline flyback converter but i just want to clarify something regarding setting up the compensation network. Figure 11 attached shows that the selection of the compensation network is dependant on the MULT and CS voltage levels, this i get. My qustion is what difference does it make to operate on the different curves? I'm guessing there are pro's & cons to each region of operation. Does the steeper curve suggest a faster response from the controller?

Thanks in advance
