摘要
A converter circuit has an error amplifier to provide an error signal; a proportional amplifier to provide a gain signal according the error signal and an output voltage of the converter circuit; a first comparator, generating a pulse signal according to the gain signal and a comparison signal; and a timer, generating a timing signal according to the pulse signal to indicate the on time and the off time of the converter circuit; and wherein either the gain signal or the comparison signal comprises a ramp component, and wherein the on time of the converter circuit is constant.
