Abstract
In a general aspect, a charging apparatus can include a power converter circuit configured to supply, from an input voltage, charging power for charging a battery of an electronic device; and a control circuit configured to determine a charging current limit and a charging voltage of the power converter circuit for charging the battery. Determining the charging current limit and the charging voltage can include: setting the current limit of the power converter circuit to an initial charging current limit and setting the charging voltage to an initial charging voltage; determining whether the power converter circuit is operating in a current limit mode or a voltage limit mode; and iteratively modifying the current limit of the power converter circuit until the power converter circuit dithers between the current limit mode and the voltage limit mode.
