Abstract
According to one embodiment, a DC/DC converter is supplied with a DC power supply voltage from a main power supply, or a backup voltage from a backup power supply, converts the DC power supply voltage to a DC conversion voltage or converts the backup voltage to a backup conversion voltage, and supplies the DC conversion voltage or the backup conversion voltage to a load. The converter includes a stop function for stopping the conversion operation of the DC power supply voltage in the converter part when the DC power supply voltage has lowered to less than a certain threshold voltage. This stop function is disabled when a backup power is supplied, and the converter continues the conversion operation of the backup voltage.
