TLV627432: SW pin absolute maximum ratings(AMR) AC value

Part Number: TLV627432

Hi team,

My customer test a -600mV on SW pin, it lasts for 40ns. In datasheet, it says the absolute maximum ratings value of SW is -300mV. I think it is a DC value, which means the SW pin can tolerate -300mV for a long time. And I wonder its AC value(last for short time).

The waveform is below.

Best Regards,

Peter

    Hello Peter,

    Thank you for reaching out,

    Yes you are right, it is a DC value and if it goes down -300mV, the device may damage.

    The absolute values for transient less than 10 ns is also specified in the datasheet.

    Thank you,

    Regards,
