Zusammenfassung:A switching power supply circuit includes a transformer, a switching unit which includes at least one switch and is connected to an output of the transformer, and a switching controller which is connected to an output of the switching unit, is configured to control the switching unit, and includes a comparing unit and an output waveform generating unit. Furthermore, the comparing unit is configured to output a value used to control the output waveform generating unit, and the output waveform generating unit is configured to generate a control signal based on the output value of the comparing unit and output the control signal to the at least one switch of the switching unit. Accordingly, the power consumption is reduced by performing rectification using a switch, and the switching power supply circuit is prepared in a simple configuration since the switching unit is controlled without any controller.
