Abstract
A method implemented by a control circuit adaptively controls operating parameters of a switched-mode power supply to compensate for variation in circuit parameters of the switched-mode power supply, such as variation of: an inductance of an inductor, a capacitance of an output capacitor, and variation of a load capacitance coupled to an output of the switched-mode power supply. The control circuit includes a comparison circuit that determines whether or not an output voltage of the switched-mode power supply has exceeded an overshoot threshold, and a switching control circuit that has an input coupled to an output of the comparison circuit. The switching control circuit adaptively adjusts a control variable that controls one or more operational parameters of the switched-mode power supply in conformity with a relationship between a value of the output voltage and a value of the overshoot threshold in response to the output of the comparison circuit.
