An integrated circuit (104) with a driving circuit for driving a load withy a DC voltage generated by a power source circuit and a voltage conversion circuit (106) for decreasing the DC voltage includes a switching circuit (109) for generating a voltage pulse using the DC voltage; an output unit configured to output the voltage pulse generated by the switching circuit (109) to a smoothing circuit provided outside the integrated circuit (104); a first input unit configured to receive a first DC voltage generated by the power source circuit; a second input unit configured to receive a second DC voltage which is generated by the smoothing circuit and is lower than the first DC voltage; and a control circuit (107) configured to operate based on a voltage decreased by the voltage conversion circuit (106), and control the switching circuit (109) and the driving circuit. |
