ABSTRACT:
In a switching power supply apparatus, an input voltage Vin applied to an input terminal is output from a first output terminal and a second output terminal after boosting or inverting of the voltage Vin. When a first and a fourth switches are turned on, a flying capacitor is charged. When a second and a fifth switches are turned on, charges charged in the flying capacitor are transferred to a first output capacitor. When a third and a fifth switches are turned on, charges charged in the flying capacitor are transferred to a second output capacitor. A voltage Vin×2double the input voltage Vin is output from the first output terminal as a first output voltage Vout1, and a voltage −Vin obtained by inverting the input voltage is output from the second output terminal as a second output voltage.
