Abstract
A control circuit for controlling a DC-DC converter is provided. The control circuit comprises a first sensor, second sensor, error amplifier, signal conditioning circuit, first comparison circuit, second comparison circuit, and driver circuit. The error amplifier is configured to receive a feedback voltage and a reference voltage for generating a first voltage. The signal conditioning circuit is configured to receive the first voltage for generating a second voltage and a third voltage. The first comparison circuit is configured to make a comparison based on a first sensing signal from the first sensor and the second voltage for generating a first comparison signal. The second comparison circuit is configured to make a comparison based on a second sensing signal from the second sensor and the third voltage for generating a second comparison signal. The driver circuit is for driving a power stage according to the first and second comparison signals.
