Hi all

Would you mind if we ask LM2576HV or LM2576?

How much is Absolute maximum ratings of FB pin?
Is it the same as Vin pin?

Kind regards,

    For the ADJ version I would limit the voltage to 6V absmax.

    For the fixed versions I would use the ratio of 6V up to the programmed Vout to set a maximum.
    If that calculation is greater than Vin; then use Vin as the maximum limit.
