Abstract

A voltage converting circuit and a control circuit thereof are provided. The control circuit includes a comparator, a clock generator, and a boost circuit. The comparator compares an input voltage with an output voltage to generate a comparison signal. The clock generator generates a clock signal according to the comparison signal to enable the clock signal to have a first frequency in a first time interval and to have a second frequency in a second time interval. The first frequency is higher than the second frequency. The first time interval occurs before the second time interval. The boost circuit receives the clock signal, pulls up a control signal of a driving switch in the first time interval according to a first driving capability, and generates the control signal in the second time interval according to a second driving capability. The first driving capability is greater than the second driving capability.
