Abstract
Disclosed are a driving circuit, a stylus and an electronic device. The driving circuit includes: a power supply assembly, at least one energy storage capacitor, a switch assembly and a driving electrode. In a driving cycle: the switch assembly is configured to control connections among the power supply assembly, the at least one energy storage capacitor and the driving electrode, so that the driving electrode outputs a first voltage, at least one second voltage and a third voltage, wherein the first voltage and the third voltage are respectively a maximum voltage and a minimum voltage output by the driving electrode, and the sum of energy storage voltages of the at least one energy storage capacitor is less than the first voltage. The driving circuit, the stylus and the electronic device of the embodiment of the present application could reduce a power consumption.
