| 1. A voltage converter, comprising:
a power stage including two or more power switches; and
a controller configured to:
determine, for a first load condition, a first output current of the voltage converter and a corresponding first time delay
through the voltage converter;
determine, for a second load condition, a second output current of the voltage converter and a corresponding second time delay
through the voltage converter; and
determine a load-dependent delay of the voltage converter based upon the first output current, the first time delay, the second
output current, and the second time delay.
