Duty cycle is determined by comparing the output of the error amplifier COMP pin and the ramp signal derived from the current sense pins. And I want to ask uc3846n, does UC adjust the uc3846n ratio uc3846n adjusting the setting voltage of the feet 5?

Hi Jenny, Duty cycle is determined by comparing the output of the error amplifier COMP pin and the ramp signal derived from the current sense pins. Uc3846m I still have two doubts about it. Uc3846h Jenny, I am not quite sure what is meant by frame-throwing phenomenon.

Could you provide some details? Thank you very much! Hi Ben Lough, Thanks for your patience. If you have further questions related to this thread, you may click “Ask uc3846n related question” below.
