Abstract
A switch-mode power supply includes a first switch circuit, at least one second switch circuit, a switch control circuit, a first inductor switching circuit, a coupled inductor, a voltage input end, and a voltage output end. The coupled inductor in the switch-mode power supply may be connected to the first switch circuit, to implement signal transmission between the coupled inductor and the first switch circuit. Signal transmission between the coupled inductor and the second switch circuit may be implemented under control of the first inductor switching circuit. Alternatively, the signal transmission between the coupled inductor and the second switch circuit may be disconnected under the control of the first inductor switching circuit.
