Abstract: The multifunctional solar charger circuit is designed with control chip CN3083 and DC conversion chip MC34063. The system converts solar energy into electric energy by using a solar panel, and then the output voltage is altered by boost circuit, voltage-stabilizing circuit and buck circuit. The battery is charged by using a protection mode of constant current, constant voltage and constant temperature. The charging process of the lithium battery is controlled by adjusting the charging current of the input terminal independently. This design can not only achieve the maximum charg-ing current, but also prevent the chip from overheating, and has the function of charging protection.
