Abstract
A duty cycle control circuit generates a duty cycle control signal for controlling the duty cycle of a DC-DC buck conversion signal. The duty cycle control circuit includes: a dual ramp generator for generating a first ramp signal and a second ramp signal having the same frequency and different phases; a first comparator for comparing the first ramp signal with a feedback signal to generate a first control signal; a second comparator for comparing the second ramp signal with the feedback signal to generate a second control signal; and a logical circuit for performing a first predetermined logical operation according to the first control signal and a first conduction-control signal to generate a first part of the duty cycle control signal, and performing a second predetermined logical operation according to the second control signal and a second conduction-control signal to generate a second part of the duty cycle control signal.
