PROBLEM TO BE SOLVED: To provide a ripple converter for generating an output voltage at a desired level even if an operation condition changes.SOLUTION: The ripple converter for generating an output voltage at a desired level from an input voltage includes: a transistor having an input electrode that receives the input voltage and an output electrode connected to an inductor, an output circuit for outputting a voltage of the output electrode when the voltage of the output electrode is lower than a threshold voltage at a predetermined level, and for outputting a threshold voltage when the voltage of the output electrode is higher than the threshold voltage, an integrating circuit for integrating voltage output from the output circuit, a feedback voltage generation circuit for generating a feedback voltage based on the voltage integrated by the integrating circuit and the output voltage, and a switching circuit for switching the transistor based on the feedback voltage so that the output voltage at the desired level is generated. |
