  • UCC24612: DCM False turn ON - LLC Sync FETs

    Part Number: UCC24612 Tool/software: Hi, We are using UCC24612-2 in LLC sync FET drive. (2 FETs, center tapped architecture). Integrated Leakage inductance in LLC transformer for Lr. We are seeing frequent false turn ON 1 of the sync FET gate pulse…

  • UCC24624: Increased FET loss due to early turn-off

    TI Thinks Resolved
    Part Number: UCC24624 Tool/software: Hi, We are currently using the UCC24624 in an LLC resonant converter and are facing a problem where the SR MOSFET gate turns OFF before the drain current reaches zero. This results in extended body diode conduction…
