1. A DC to DC conversion circuit comprising:
a DC to DC converter connected to an input path and an output path; and
a current limiting circuit comprising:
a circuit configured to detect when an input or output current of the DC to DC converter exceeds or falls below a current threshold; and
a controller configured to:
store a first voltage level of an output voltage of the DC to DC converter in response to the input or output current exceeding the current threshold;
store a second voltage level of the output voltage in response to the input or output current falling below the current threshold; and
set a control signal based on the first and second voltage levels.
