LM5143-Q1: ABSOLUTE MAX VOLTAGE OF LM5143

Part Number: LM5143-Q1
Other Parts Discussed in Thread: LM5143, LM5137F-Q1, LM5137-Q1

Tool/software:

Hi,

In datasheet of LM5143, absolute maximum input voltage (Vin to PGND) was given as +70V.  Can I know how long (transient condition) the IC withstands the absolute maximum voltage of +70V?

  • Hi Ragul,

    We don't advise exceeding the operating maximum of 65V, particularly as this is also the SW voltage maximum. If you need higher voltage rating, consider the LM5137-Q1 (we currently have the functional safety version, LM5137F-Q1, online).

    Regards,
