Abstract:
A control circuit and method for a voltage converter. The control circuit having a ramp circuit, a reference generating circuit, a comparison circuit and a logic circuit. The ramp circuit generates a ramp signal that decreases from the moment the power switch is turned off and increases from the moment the power switch is turned on. The reference generating circuit generates a reference voltage. The comparison circuit compares the reference voltage with the sum of the feedback voltage and the ramp signal to generate a comparison signal. The logic circuit uses the comparison signal and a clock signal to generate the control signal to control a power switch of the voltage converter.

Claim (Index 1):
A control circuit for a voltage converter converting an input voltage into an output voltage, wherein the voltage converter has a power switch, the control circuit comprising:\n a ramp circuit, configured to generate a ramp signal, wherein the ramp signal decreases from a moment the power switch is turned off and increases from a moment the power switch is turned on; a reference generating circuit, configured to generate a reference voltage, wherein the reference voltage increases from a value of a base voltage when the power switch is turned off, wherein the base voltage is regulated based on a feedback voltage and a source voltage, and the source voltage has a constant voltage level; a comparison circuit, configured to provide a comparison signal in response to the reference voltage and a sum of the feedback voltage and the ramp signal; and a logic circuit, configured to generate a control signal to control the power switch based on the comparison signal and a clock signal with constant frequency, wherein the power switch is turned off by the clock signal, and is turned on when the comparison signal indicates that the reference voltage increases to the sum of the feedback voltage and the ramp signal.
