1. A control circuit comprising:
a gate driver circuit to receive a first plurality of primary-side switch control pulses and to generate a first plurality of primary-side gate control pulses therefrom to control a gate node of a primary-side switch of a power converter; and
a gate drive control module to provide a switch transition speed control signal to the gate driver circuit to control a switch transition speed of the primary-side switch of the power converter for each pulse of the first plurality of primary-side gate control pulses;
wherein the gate drive control module is configured to set the switch transition speed of the gate driver circuit to a first speed for generating one or more initial pulses of the first plurality of primary-side gate control pulses and is further configured to set the switch transition speed of the gate driver circuit to a second speed for generating one or more subsequent pulses of the first plurality of primary-side gate control pulses.
