1. An apparatus comprising:
a switching circuit comprising:
an input configured to accept an input voltage;
at least one switch coupled between the input of the switching circuit and an output of the switching circuit, the at least one switch configured to selectively:
be in a closed state to connect the input to the output; or
be in an open state to disconnect the input from the output;
at least one driver circuit coupled to the at least one, the at least one driver circuit configured to provide a driver current to enable the at least one switch to transition from the closed state to the open state; and
at least one driver controller coupled to the at least one driver circuit, the at least one driver controller configured to:
monitor at least one parameter associated with the input voltage;
detect a change in the at least one parameter; and
adjust a magnitude of the driver current provided by the at least one driver circuit based on the detected change in the at least one parameter, wherein:
the at least one parameter is configured to selectively have a first magnitude or a second magnitude that is smaller than the first magnitude;
the at least one driver circuit is configured to selectively:
provide a first driver current as the driver current; or
provide a second driver current as the driver current, the second driver current being smaller than the first driver current;
the at least one driver controller is configured to selectively:
cause the at least one driver circuit to provide the second driver current responsive to the at least one parameter having the first magnitude; or
cause the at least one driver circuit to provide the first driver current responsive to the at least one parameter having the second magnitude;
the input is configured to accept an input current;
the input voltage comprises a direct-current supply voltage; and
the at least one parameter includes the input current and the direct-current supply voltage.
