Zusammenfassung:	This application relates to the field of circuit technologies, and provides a step-up circuit and a step-up circuit control method. The step-up circuit includes a power supply, an inductor, N switch components, N-1 flying capacitors, N flyback diodes, a pre-charge unit, and an output unit. The N switch components are connected in series, a first switch component of the N switch components is connected to a first terminal of the power supply through the inductor, and an Nth switch component is connected to a second terminal of the power supply. At least two switch components of the N switch components have withstand voltage specifications different from each other. Values of voltages withstood by switch components with different withstand voltage specifications during normal operation are also different from each other. N is a positive integer.
