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 12):
A method of controlling a voltage converter to convert an input voltage into an output voltage, wherein the voltage converter comprises at least a power switch, the method comprising:\n turning off the power switch by a clock signal with constant frequency; generating a ramp signal and a reference voltage, 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, and the reference voltage increases from a value of a base voltage from a moment 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; comparing the reference voltage with a sum of the feedback voltage and the ramp signal, wherein the feedback voltage is in proportion to the output voltage; and turning on the power switch when the reference voltage reaches the sum of the feedback voltage and the ramp signal.
