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 10):
A control circuit of a switching power supply, the control circuit comprising:\n a) a ramp circuit configured to generate a ramp signal according to an output feedback signal of said switching power supply, and to make an amplitude of said ramp signal follow said output feedback signal; b) a judgment circuit configured to judge whether said ramp signal reaches a peak value, and to generate a switching control signal; and c) when said ramp signal reaches said peak value, said switching control signal being configured to pulse in order to change the switching state of main power switch in said switching power supply, such that an output signal of said switching power supply is maintained substantially constant.
