Hi Mars:
unfortunately, UCC28070 samples PFC mos on current to do the control, so you can not change the current sample location you listed.

Hi Mars:
From my experience, I suggest using at least >2MHz Gain bandwidth AMP.
By the way, if you choose Resistor samples current under mosfet S pin, please pay special attention to the MOSFET Driving circuit's layout. That is because the voltage on the resistor may influence the VGS of mosfet.
