Claim 0:
1. A gate control circuit for regulating a gate-drive voltage to a gate of a power FET, including:
(a) a source-follower circuit including a source-follower FET having a conduction channel configured to be coupled to the gate of the power FET, the gate control circuit configured to selectively apply at least a first gate-drive voltage or a second gate-drive voltage to the gate of the power FET such that a current flow through the power FET in an ON state is limited when the second gate-drive voltage is applied; and
(b) a feedback circuit coupled to a gate of the source-follower FET and configured to generate a feedback signal as a function of the current flow through the power FET and to regulate the second gate-drive voltage as a function of the generated feedback signal.
