TPS55340: Could be a drop-in replacement of TPS55330?

Part Number: TPS55340
Other Parts Discussed in Thread: TPS55330

Hello,

My customer is facing delivery issue of TPS55330RTER.Looking at TPS55340 datasheet, TPS55340RTER looks the same package, WQFN(16), and pin assignment.
TPS55340 Vin range is wider than TPS55330.
Could the TPS55340MRTETEP be a drop-in replacement of the TPS55330RTER without changing any peripheral components?
Or it is not so straight forward?

Best regards,

K.Hirano

    Hi K. Hirano,

    Thank you for your question.

    As you notice correctly, both the TPS55330 and TPS55340 have the same specifications and pin layout, with the main difference being the larger Vin range of the TPS55340.
    Because of this, the TPS55340 can indeed be used as a drop-in replacement without changing other parts of the circuit.

    I would still suggest to run some tests with the new part, just to make sure the IC behaves exactly like with the old part, but there shouldn't be any major differences.

    Best regards,
    Niklas

    Hi K. Hirano,

    as there are no further comments form you or the customer side, I will close the thread for now.
    If additional question on the implementation of the drop-in part come up, feel free to reply below to re-open the thread, or create a new one.

    Best regards,
    Niklas
