A switch controlling circuit, which comprises: a frequency programmable clock signal generator and a plurality of registers. The frequency programmable clock signal generator serves to generate a frequency controllable clock signal. The registers comprises: a first stage register, for receiving an input signal and the frequency controllable clock signal, and for outputting a first output signal, which is utilized to control a first switch device, according to the input signal and the frequency controllable clock signal; and a second stage register, for receiving the first output signal and the frequency controllable clock signal, and for outputting a second output signal, which is utilized to control a second switch device, according to the first output signal and the frequency controllable clock signal.
