  • RE: UCC256404: PFC OFF standby mode

    Hi Marco, The PFC ON/OFF feature is not present in the UCC25640x series. I will get this table updated as that row is incorrect. If you use our UCC28056 along with the UCC25640x you can achieve ultra-low standby power as shown in PMP21251 . This feature…

  • RE: UCC24624: Switching Frequency above 625kHz - what's going to happen?

    Resolved
    Hi Andre, You could place a PNP transistor in between the VDD pin of UCC24624 and its voltage bias. You could then use a circuit such as what is shown in PMP21251 but instead of doing OCP, use it to turn on or off the transistor to enable/disable UCC24624…
