PROBLEM TO BE SOLVED: To provide a multiple output power supply unit capable of optimum efficiency for each output, and concurrent shutdown and oscillation between respective outputs. SOLUTION: Various types of power circuits (200-1 to 200-4), connected to a power supply, are provided respectively. The various types of power circuits include the function of outputting a failure signal to the other various types of power circuits, when a self-circuit has some failures and stopping the operation of the self-circuit, corresponding to the failure signal from any other various type of power circuits; and the function of outputting a synchronous oscillation signal which is synchronous with a switching oscillation frequency, used to control the self-circuit to the other various types of power circuits and a switching frequency, used to control the other power circuits.
