  • UCC24612: VGS is unstable under DCM

    TI Thinks Resolved
    Part Number: UCC24612 Hi Team, My customer is using UCC24612 in the boost topology, they find that SR's VGS is easier to be interfered under DCM compared to operating in CCM. What's the possible caust? CH1:SR MOSFET VGS CH2:Main MOSFET VGS …

  • UCC24612: UCC24612 for symmetrical supply

    Part Number: UCC24612 Dear Experts, I want to make +/-21V output for an LLC PSU. I built the prototype but it seems that the bridge rectifier does not work. I can se only a little signal across VD-VS pins. It looks like the MOSFETs body diodes work only…
