1. A method of controlling a switch driver, the method comprising:

  • energizing a first inductor in a first direction with a first energy;

    transferring the first energy from the first inductor to a second inductor, wherein the second inductor is coupled between a second switch-driving terminal of the switch driver and a second internal node, and the second inductor is magnetically coupled to the first inductor;

    asserting a first turn-on signal at the second switch-driving terminal using the transferred first energy;

    energizing the first inductor in a second direction opposite the first direction with a second energy after asserting the first turn-on signal at the second switch-driving terminal;

    transferring the second energy from the first inductor to the second inductor; and

    asserting a first turn-off signal at the second switch-driving terminal using the transferred second energy.
