What is the main advantage of the FAN7530 over current-mode controllers?
It does not need to detect the rectified AC line voltage, which reduces power loss in the sensing network.
From: FAIRCHILD AN-6027 Manual
How is the MOSFET turn-off instant determined?
It is determined by comparing the output of the error amplifier with the output of the sawtooth generator.
