Abstract:
1. A switching control device for supplying power to a load connected to an output, comprising: a switching element; a load state detection unit for detecting a state of a load connected to the output; and a control circuit for controlling ON/OFF of the switching element, wherein the control circuit comprises a triangular wave generation circuit and a triangular wave specified value generation circuit, wherein the triangular wave specified value generation circuit is for generating an upper limit or a lower limit of a triangular wave from the triangular wave generation circuit, wherein the upper or lower limit increases or decreases according to the state of the load detected by the load state detection unit, so that a frequency of an output signal or an input signal of the switching element is dispersed, or a jitter occurs in a frequency of an output signal or an input signal of the switching element.
