Claims4
An electronic device comprising:
- an energy storage unit;
- a charge pump circuit, electrically connected to a power supply to receive an input electrical energy from the power supply, wherein the charge pump circuit selectively directly outputs the input electrical energy or converts the input electrical energy to a converted electrical energy to a converted electrical energy to output;
- a charging circuit, electrically connected between the charge pump circuit and the energy storage unit to receive the input electrical energy or the converted electrical energy;
- and
- a controller, electrically connected with the power supply, the charge pump circuit, and the charging circuit, respectively, the controller controls the charge pump circuit and the charging circuit to switch among a plurality of charging modes according to compatibility information of the power supply;
- wherein the charging modes further include a normal charging mode, when the controller switches the charge pump circuit and the charging circuit to the normal charging mode, the charge pump circuit is not actuated and the charge pump circuit directly transfers the input electrical energy to the charging circuit, and the charging circuit adjusts the voltage of the input electrical energy to generate and output a charging electrical energy to the energy storage unit, and the energy storage unit is charged via the charging electrical energy.
