Abstract
A power control method for a charging system includes: detecting a power signal and an input voltage of the power signal; determining a charging protocol supported by the power signal; and determining whether to conduct a power switching circuit or not according to the input voltage of the power signal and the charging protocol supported by the power signal to provide power for an amplifier chip of the charging system.
Claims14
A power control method for a charging system, comprising:
- detecting a power signal and an input voltage of the power signal;
- determining a charging protocol supported by the power signal;
- and
- determining whether to conduct a power switching circuit or not according to the input voltage of the power signal and the charging protocol supported by the power signal to provide power for an amplifier chip of the charging system;
- wherein the power switching circuit is parallel to a boosting circuit.
