Abstract
A voltage converter and a control circuit thereof are provided. The control circuit includes a voltage status comparator and a control signal generator. The voltage status comparator receives an input voltage and an output voltage, and provides a base voltage. The voltage status comparator compares voltage values of the output voltage and the input voltage or compares voltage values of the output voltage and the base voltage according to a voltage status of the input voltage, and generates a comparison result. The voltage status comparator generates a bias voltage according to the comparison result. The control signal generator generates a control signal according to the bias voltage and transmits the control signal to a control terminal of a driving switch, where the driving switch is turned on or cut off according to the control signal.
