A fast power switch comprises one or more field-effect transistors, such as pull-up and pull-down transistors, that are coupled to a load. Respective driver electronic circuits for each of the field-effect transistors include parallel first and second drivers with a shared driver output coupled to a gate of the field-effect transistor. The first and second drivers are operative to switch the shared driver output for the appropriate field-effect transistor in response to a transition (e.g., low-to-high or high-to-low) at a driver input terminal. A control circuit enables the stronger second driver in response to a transition at the driver input terminal and subsequently disables the second driver once a transition threshold at the gate of the field-effect transistor(s) is crossed. The weaker first driver is sized to damp reactive energy at the load to minimize ringing.
