Abstract
A switching power supply circuit, which can respond to a rapid and large change in a load quickly and stably and ensure a power supply output having a predetermined voltage, is provided. In the power supply circuit which supplies an input current to a load while switching the input current periodically and controls an output voltage Vo supplied to the load to a predetermined target value by controlling an ON/OFF time ratio (t/t) of the switching variably, a control of the ON/OFF time ratio is performed for every one current supply cycle T independently.
