ABSTRACT:
It is an object of the present invention to reliably avoid problems with a load connected when stopping the operation of a charge pump circuit. The charge pump circuit is provided with a first switching element (S1) connected to a power supply, a second switching element (S2) connected to a load (102)and a capacitor element (Cp) connected between the first switching element (S1) and the second switching element (S2), and moves charge in a direction opposite to the direction in which charge moves during normal operation by inverting the phase of any one of clock signals applied to the first switching element (S1), second switching element (S2) and capacitor element (Cp) during normal operation.
