ABSTRACT:
A voltage converter is provided. The voltage converter generates an output voltage signal and comprises a controller, a wave generator, a comparator, and a voltage converting unit. The controller generates a control voltage signal according to the output voltage signal and a first reference voltage. The wave generator generates a saw-wave signal and modifies at least one of an upper limit and a lower limit of a waveform of the saw-wave signal according to the output voltage signal. The comparator generates a pulse width modulation (PWM) signal according to the control voltage signal and the saw-wave signal. The voltage converting unit generates the output voltage signal according to the PWM signal.
