Abstract
According to various embodiments, a method for operating a switching converter includes determining an operating parameter of the switching converter and, if the operating parameter is outside a first operating range, adjusting a control parameter in order to adjust the operating parameter to be within the first operating range. The operating parameter includes at least one of a switching frequency of the switching converter and a current ripple value of an output current.

19. A switching converter comprising:
-
a switching unit configured to be coupled to an energy storage element; an average current controller coupled to the switching unit and configured to maintain an output current to the energy storage element having a substantially constant average value; and a frequency ripple controller coupled to the switching unit and configured to; determine a switching frequency of the switching converter, determine a current ripple value of the output current from the switching converter, wherein the current ripple value comprises a difference between a maximum value of the output current and a minimum value of the output current, and adjust the current ripple value and the switching frequency if either the current ripple value is outside of a first current ripple range or the switching frequency is outside a first frequency range. - View Dependent Claims (20, 21, 22)
