    Hello,

    1. The UCC24624 can be used for an LLC full bridge.  It uses Rdson and Vdson to control the gate drive based on the FET current for LLC applications.  It should not matter if it is a half bridge or full bridge.

    2. Phase shifted full bridge and traditional full bridge can general be self driven from the secondary and should not require a driver.  The UCC24624 was really designed for LLC applications.

    3. The UCC24624 was optimized for LLC applications.  However, it could function as a half bridge driver.

    4. If the half bridge has a PFC pre-regulator you may also consider using self driven.

    Regards,
