1. An apparatus for controlling a switch, the apparatus comprising:
a difference signal circuitry configured to detect a voltage across the switch;
a reference signal circuitry configured to generate a current reference signal based on the voltage across the switch;
a feedback current circuitry configured to receive a feedback current signal representing a current level in the switch; and
a control circuitry configured to provide a control signal for the switch based, at least in part, on a difference between the current reference signal and the feedback current signal.
