Adaptive slew rate control for switching power devices

A method of adaptive slew rate control, comprising:

• coupling a high pass filter (HPF) between an output (OUT) of an output stage and a ground, said output stage comprising at least one switching transistor which provides a voltage output (Vout) having a control node of said switching transistor driven by a gate driver that includes at least one driving transistor, wherein there is an adjustable current source in series with said driving transistor;
• during a switching transition of said switching transistor, said HPF detecting a slew rate of said switching transistor as a voltage pulse (Vslp) having a peak voltage amplitude that at least monotonically reflects a slope of Vout during said switching transition;
• signal processing said Vslp to output a processed detection signal;
• comparing said processed detection signal to a high reference level that reflects an upper slew rate limit and to a low reference level that reflects a lower slew rate limit, and
• changing a current level of said adjustable current source to change said slew rate of said switching transistor so that a resulting adjusted slew rate of said switching transistor is set between said lower slew rate limit and said upper slew rate limit.
