Abstract: A method for limiting an input or output current of a DC-DC converter and a current limiting circuit are disclosed. In an embodiment a method for limiting an input or output current of a DC to DC converter includes storing a first value representative of a level of an output voltage of the DC to DC converter in response to the input or output current exceeding or falling below a first threshold and modifying a control signal based on the first value.
