Claim 21:
22. The load control device of claim 21, wherein the first closed-loop gate drive circuit comprises:
a first target signal set circuit configured to:
receive a turn-on signal from the turn-on wave-shaping circuit and receive a turn-off signal from the turn-off wave-shaping circuit,
receive a step signal from a first step-up circuit a predetermined time after receiving the first drive signal from the control circuit, and
generate the first target signal based on one or more of the turn-on signal, the turn-off signal, and the step signal; and

wherein the first closed-loop gate drive circuit is configured to generate the first gate control signal in response to the first target signal and the drain-source current through the first semiconductor switch.
