TPS40210 using at ambient temperature of 115 degree Celsius

Other Parts Discussed in Thread: TPS40210

Is it possible to use TPS40210 above Tjunc of 125 degree?
Customer has ambient temperature of 115 degree and need therefore some additional temperature margin.
Is there a restriction by thermal shutdown or is it only derivation of electrical specification?

Any help welcome

Best Regards

Josef

    The TPS40210 controller has an absolute maximum junction temperature of 150C and no over-temperature protection.

     

    The datasheet specifications are only valid for junction temperatures to 125C, so while the IC will function, some parameters may be outside their datasheet specifications.
