LM5072: Questions of LM5072

Jimmy Lai

Part Number: LM5072

Dear Team,

Could you help to confirm the actual voltage range of LM5072 pin10, VCC
According to the spec, it is 16V, but we actually tested it to 25V to make the LM5072 broken
If we use 20V to supply power to VCC
May I ask if the LM5072 can support it?

Many Thanks,

Jimmy

    Hello Jimmy,

    Because of the Thanksgiving holiday in the U.S., TI E2E design support forum responses may be delayed this week. Thank you for your patience.

    Hi Jimmy,

    Please make the VCC-ARTN always below 16 V.

    Sometimes beyond the max voltage rating (even in transient) won't cause instant failure but slow degradation.

    Updated on Jan/17/2023: It has been a relatively long period that we have not received your reply. I will close this thread for now. Please open a new thread if you have further questions.

    Best regards,
