PROBLEM TO BE SOLVED: To constitute an arrangement for varying the output voltage to a specified voltage in a minimum necessary time while satisfying the order for starting or stopping a plurality of power supply outputs such that it can be incorporated in a small IC. SOLUTION: The multi-output power supply 1 comprises voltage converting sections P0-P2 generating various voltages based on an input voltage VIN. When the output voltage VOUT0 from the voltage converting section P0 reaches a specified voltage, a control signal generating section VM1 varies a control signal CTL1 actively. The voltage converting section P1 is turned on by variation of its control signal CTL1 to deliver an output voltage VOUT1. When the output voltage VOUT1 reaches a specified voltage, a control signal generating section VM2 varies a control signal CTL2 actively. The voltage converting section P2 is turned on by variation of its control signal CTL2 to deliver an output voltage VOUT2. COPYRIGHT: (C)2006,JPO&NCIPI
