Abstract
A step-down circuit, an electronic device, and a step-down method are disclosed. The step-down circuit includes a positive input terminal and a negative input terminal for receiving an input voltage; and a positive output terminal and a negative output terminal for outputting a target voltage. The negative input terminal and the negative output terminal are grounded together. The step-down circuit also includes a switch circuit, a rectifier circuit, an isolation circuit, and a control unit for outputting control signals to control for turning on or off a switch in the switch circuit and for turning on or off a switch in the rectifier circuit, allowing the input voltage to sequentially pass through the switch in the switch circuit, a capacitor in the isolation circuit, and the switch in the rectifier circuit to obtain a target voltage.
