TPS7A24: TPS7A2433DBVR schematics review

Part Number: TPS7A24

Tool/software:

Hi.

Please help TPS7A2433DBVR schematics review, thanks!

  • Hello Kevin,

    The power dissipation across the pass element is too high and will cause the device to enter into thermal shutdown almost immediately. The Junction-to-ambient thermal resistance of the package is 167.8°C/W and at 1.74 watts [(Vin - Vout)*Iout], the die temperature will exceed 300 C. It is recommended to reduce the input voltage with a buck converter or reduce the  load current.

    Best regards,

    Daniel E.
