特徴とするＤＣ―ＤＣコンバータ。 A voltage conversion circuit is provided in which a switching element and a coil are connected in series, and the switching element is turned on/off while a DC voltage is applied to the voltage conversion circuit to generate a back electromotive voltage in the coil. In a DC-DC converter that extracts and outputs this back electromotive voltage, a control circuit that controls on/off of the switching element and a voltage change obtained at the connection point between the switching element and the coil are A DC-DC converter comprising a feedback loop circuit that feeds back to a control circuit to perform an oscillation operation.
