Abstract

A method and apparatus for performing adaptive input current control in an electronic device are provided, where the method may include the steps of: before limiting an input current of a regulator of the electronic device to a target current value, monitoring the input current of the regulator according to a reference current, and decreasing the reference current, to make the reference current change starting from one of a plurality of predetermined reference current values, wherein the input current is obtained from a power source; detecting an input voltage of the regulator to generate a detection signal, to selectively trigger limiting output power of the regulator; and at a time point when the reference current becomes smaller than the input current, limiting the input current of the regulator to the target current value with a latest reference current value of the reference current being utilized as the target current value.
