Abstract: A method for controlling a switched-mode power supply having a current limiting control for limiting output current of the switched-mode power supply to a predetermined maximum limiting current value, and having a current boost control for setting the predetermined maximum limiting current value to a predetermined overcurrent value for a predetermined boost time.
