VOLTAGE CONVERSION CHIP AND ELECTRONIC DEVICE

Embodiments of the present application provide a voltage conversion chip and an electronic device, applied to the technical field of integrated circuits. A switch circuit, a current detection circuit, a duty cycle adjustment circuit, a driver, an oscillator, and a voltage feedback circuit are provided in the voltage conversion chip. An input port and an output port are coupled by means of the switch circuit. An output end of the voltage feedback circuit is coupled to a first input end of the driver. An input end of the duty cycle adjustment circuit is coupled to the oscillator. An output end of the duty cycle adjustment circuit is coupled to a second input end of the driver. The current detection circuit is further coupled to the duty cycle adjustment circuit. A duty cycle of a clock signal output by the duty cycle adjustment circuit can be adjusted by means of a detection signal of the current detection circuit. The driver controls the switch circuit according to the clock signal and a voltage signal output
