Abstract

An electronic device may include a load and a power management circuit configured to manage power provided to said load. The load may include a memory for storing instructions and at least one processor. When the instructions are executed individually or collectively by at least one processor, they may cause the electronic device to identify a minimum mode to be applied to the operation of the power management circuit among a plurality of operating modes of the power management circuit. The minimum mode may be a mode having the lowest maximum power among at least one operating mode to be applied to the power management circuit while providing the power to said load in the power management circuit. When the instructions are executed individually or collectively by at least one processor, they may cause the electronic device to provide the power to said load in the power management circuit by applying a mode greater than or equal to the minimum mode. When the above instructions are executed individually or collectively by at least one processor, they may cause the electronic device to count the number of occurrences of an overpower protection event detected by the power management circuit. When the above instructions are executed individually or collectively by at least one processor, they may cause the electronic device to determine whether the lowest mode of the power management circuit can be raised based on the fact that the number of occurrences is greater than or equal to a reference value. When the above instructions are executed individually or collectively by at least one processor, they may cause the electronic device to raise the lowest mode of the power management circuit by determining a mode higher than the current lowest mode as the lowest mode based on the fact that the lowest mode can be raised. In addition, various other embodiments are possible.
