25. A system comprising:
a power converter configured to:
receive an input voltage and generate an output voltage; and
operate in a bypass mode in which a bypass switch couples an output of the power converter configured to generate the output voltage to an input of the power converter at which the input voltage is received; and
a controller configured to:
control operation of the power converter based on a comparison of a current associated with the power converter to a threshold current;
control the threshold current as a function of the input voltage; and
set the at least one output voltage threshold to the first magnitude in response to the power controller entering the bypass mode.
