PROBLEM TO BE SOLVED: To provide a switching power supply device and air conditioner, capable of reducing power consumption in a standby operation mode, in a multi output type switching power supply device in which a plurality of load circuits are connected to the output side.SOLUTION: For a load circuit 10c with a load 14 requiring power supply in a standby operation mode, an output voltage is set to 5 V that is the lowest one of voltages of a supply load required in the standby operation mode. In the load circuit 10c, for a load 15 requiring a higher load voltage than the output voltage that is 5 V in a normal operation mode, boosting means, such as a boosting converter 21, boosts the output voltage for supply. |
