Abstract: Methods and apparatus for controlling a switch transition in an inductive switching circuit are disclosed. A switch driver is configured to receive an indication of current through a diode associated with a first switch and dynamically control a switch transition of a second switch based on the indication of current, so as to reduce the switch transition time, when possible, whilst maintaining a voltage transient due to the switch transition within an acceptable range.
