PROBLEM TO BE SOLVED: To provide a power supply device having good response and can accommodate a wide range of applications.SOLUTION: Based on the output voltage of a DC-DC converter and a target value thereof, or based on the output current of a DC-DC converter and a target value thereof, an operation amount is created, and then PWM control or PFM control is performed based on the operation amount. The operation amount includes one or a plurality of elements out of a proportional element, an integral element and a differential element, and the gain related to at least one element is adjusted based on the operation amount created immediately before. |
