ELECTRONIC DEVICE AND METHOD FOR CONTROLLING POWER IN ELECTRONIC DEVICE

An electronic device according to various embodiments may comprise: a power management unit which supplies power to components of the electronic device and includes an under-voltage lockout circuit that monitors an input voltage of the power management unit and operates to turn off the power of the electronic device when the input voltage is determined as a first voltage; a power compensation circuit which detects the input voltage of the power management unit and supplies power to the power management unit or stores power to be supplied to the power management unit on the basis of the input voltage of the power management unit; and a processor configured to supply the power stored in the power compensation circuit to the power management unit so that the under-voltage lockout circuit does not operate when the input voltage of the power management unit detected by the power compensation circuit is determined as the first voltage. Various other embodiments may be provided.
