Abstract
Controlling a switching power supply can include: generating a ramp signal having an amplitude that follows an output feedback signal of the switching power supply; and controlling a switching state of a main power transistor in the switching power supply to be switched when the ramp signal reaches a peak value such that an output signal of the switching power supply is maintained as substantially constant.
