Abstract

A switching device for driving a load is provided. The switching device comprises a control terminal and has a conduction threshold which, when crossed by a control signal coupled to the control terminal, causes the switching device to conduct. A control circuit for generating the control signal is also provided. The control circuit is configured to generate a control signal having a first slew rate prior to the control signal crossing the conduction threshold and a second slew rate after the control signal has crossed the conduction threshold. The first slew rate may be faster than the second slew rate.
