Abstract:
According to the present invention, a power supply circuit that charges a battery and supplies power to a load circuit includes: a DC/DC converter that converts power of a first direct-current voltage supplied from an external power supply to power of a second direct-current voltage and supplies the power of the second direct-current voltage to the load circuit; a charging control circuit that is connected to the external power supply in parallel with the DC/DC converter, converts power of the first direct-current voltage to power of a third direct-current voltage, and supplies the power of the third direct-current voltage to the battery; and a switch circuit that switches between a first mode in which power is supplied from the DC/DC converter to the load circuit and a second mode in which power is supplied from the battery to the load circuit.
