Abstract
A switching control circuit for controlling a power supply circuit that includes an inductor to which an input voltage is applied and through which an inductor current flows, and a transistor configured to control the inductor current. The switching control circuit includes first and second error voltage output circuits that output first and second error voltages, based respectively on a feedback voltage corresponding to the output voltage and a reference voltage, and on an error signal corresponding to a difference between the level of the output voltage and a second level, when the power supply circuit is of a non-isolated type and an isolated type, respectively. The switching control circuit further includes a drive circuit that switches the transistor based on the inductor current, and on the first and second error voltage when the power supply circuit is of the non-isolated type and an isolated type, respectively.
