An adaptive driver includes a gate driver having at least one driving transistor for driving a control node of switching transistor(s) that includes an output node (OUT) which provides Vout. An adjustable current source is in series with the driving transistor, a high pass filter (HPF) is between OUT and ground for detecting a slew rate of the switching transistor and outputting a voltage pulse (Vslp) output having a peak voltage amplitude at least monotonically reflecting a slope of Vout during switching. Detection signal processing circuitry is coupled to the output of the HPF for processing Vslp and slew rate control circuitry has an input coupled to the output of the detection signal processing circuitry. The output of the slew rate control circuitry is coupled to the current source for controlling its current level for changing the slew rate of the switching transistor to provide a desired slew rate range.
