Abstract
A converter control circuit for converting an input voltage to an output voltage comprises: an error amplifier, coupled to an output voltage or a feedback output signal from the output voltage, and a reference signal, operable to generate an error signal accordingly; a ramp signal generator, generating a first ramp signal and a second ramp signal; a first comparator, coupled to the error signal and the first ramp signal, operable to generate a first comparing signal accordingly; a second comparator, coupled to the error signal and the second ramp signal, operable to generate a second comparing signal accordingly; and a control signal generator, coupled to the first comparing signal and the second comparing signal, operable to generate a control signal to turn switches in the converter circuit ON and OFF accordingly.
