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.

Claim (Index 15):
The control circuit of  claim 14 , wherein said ramp generating circuit comprises:\n a) a charging current generator configured to generate a charging current that represents a difference between said compensation signal and said sense signal; b) an energy storage element having a first terminal for receiving said output feedback signal, and a second terminal being charged by said charging current, wherein a voltage at said second terminal of said energy storage element is taken as said ramp signal; c) a switching circuit coupled between said first and second terminals of said energy storage element, and being controlled by said switching control signal; and d) when said ramp signal reaches said second voltage, said switching control signal is configured said switching circuit to turn on, and to coupled said first and second terminals of said energy storage element in short, such that said ramp signal is reset to said output feedback signal and rises again.
