  • RE: UCC3895: slope compensation circuit

    Resolved
    Hello, I gave this some thought last week and I don't believe this slope compensation circuit is that good. I would recommend using a high instead. divider off of CT instead. 1. Remove Q1 and Connect R1 to CT. 2. Disconnect R2 from CST and connect…

  • RE: UCC28951: What is the current sense level to trigger the hiccup?

    Hi Lauren You are correct, but there are some other things to consider. The hiccup procedure will stop and normal operation resume if the ILIM condition is removed before the SS capacitor has been discharged to the 3.6V threshold. The hiccup can be prevented…
