Abstract
Multi-phase interleaving control of a power supply device is accelerated. Furthermore, in accelerating the multi-phase interleaving control in the power supply device, detection of feedback signal is accelerated. In the power supply device and a method for controlling the power supply device, output voltage is acquired as an operation result of a discrete time process using an initial value of the output voltage at a predetermined point, and a detection value of capacitance current at each point of the discrete time process. Accordingly, only detection of the initial value is performed when the output voltage being slow in response is acquired, and detection performed in the discrete time process can be accomplished by detection of capacitance current being rapid in response, thus enabling rapid response.
