A voltage converter is disclosed. The voltage converter includes a constant on time signal generator, a first and second transistors, an inductor, a feedback circuit and a ripple injection circuit. The constant on time signal generator generates a first and second driving signals for driving the first and second transistors. The voltage converter generates an output signal at an output end thereof. The feedback circuit divides the output signal to generate a feedback signal at a feedback end of the voltage converter. The ripple injection circuit gets the voltage of the feedback end and the voltage of the phase end to generate a injection signal. The constant on time signal generator generates the first and second driving signals according to the injection signal, the output signal and a reference signal.
