Abstract
A DC-DC converter including an output stage, a feedback loop, a pulse-width modulation (PWM) generating circuit, and a driving circuit is disclosed. The output stage is coupled to an input voltage and an output inductor to provide an output voltage. The feedback loop is coupled to the output inductor and receives the output voltage to generate a control signal. The PWM generating circuit is coupled to the feedback loop and receives the control signal. The PWM generating circuit also includes a timing signal generating unit which makes the PWM generating circuit to generate a PWM signal according to a correction voltage. The correction voltage is reacted in the output voltage and a first current source related to the input voltage. The driving circuit is coupled to the output stage and the PWM generating circuit and receives the PWM signal to control the operation of the output stage.
