Abstract
A method includes detecting a signal on a switching node connected to a power switch, detecting a gate drive voltage of the power switch, during a gate drive process of the power switch, reducing a gate drive current based on a first comparison result obtained from comparing the signal with a first threshold, and during the gate drive process of the power switch, increasing the gate drive current based on a second comparison result obtained from comparing the gate drive voltage with a second threshold.
