Beschreibung
Zusammenfassung:	This invention relates to a high step-up ratio circuit, including a first charge pump, a second charge pump, a conductive inductor, a voltage boost circuit, and an output circuit. The first charge pump has a first switch element, a second switch element, and a first voltage boost capacitor. The second charge pump has a third switch element and a second voltage boost capacitor. The conductive inductor connects with the first voltage boost capacitor and second voltage boost capacitor. The voltage boost circuit has a fourth switch element, a fifth switch element, and a third voltage boost capacitor. The conductive inductor connects the first voltage boost capacitor and the second voltage boost capacitor. The output circuit is coupled with the third voltage boot capacitor. The high step-up ratio circuit is driven to be conducted or not conducted by the band width adjustment control signal through those switch elements and in conjunction with those voltage boost capacitors to boost the input voltage and then outpu
