  • RE: LM5039: Searching isolated driver IC for LM5039

    Resolved
    Hi Eric, THANK YOU But I think LM5110-1M is not what customer want, cause LM5110-1M is not isolated driver IC I found an IC here UCC21542 . Is it applicable to be isolated driver IC for LM5039 ? Is there anything to pay attention to? THX

  • RE: LM5035: There is a small spike in output voltage when the half-bridge circuit based on LM5035 starts

    Hello again, Thank you for taking the 'scope pictures. Very nice documentation! I think there are two issues at work here; 1) The very, very long soft start time. 2) The 7.5V rail is sagging. When 7.5V drops below ~(3.0Vtyp, 3.5Vmax) the LM5110 detects…

  • RE: LM5035: Two abnormal phenomena during the startup and shutdown of half-bridge power supply based on LM5035

    Resolved
    Hi zoujiangyilang, Sorry for the long time delay. There is already DC block capacitor at primary side, C20 and C23 is not necessary here in my opinion. I am not very sure why designer added C20 and C23 here, maybe it is for quick turn off. Could you check…
