TPS2121: Adapter board to prototype VQFN-HR 12 (TI's RUX) package?

Part Number: TPS2121

Is there an adapter board to prototype the RUX package?

Would also be interested in a "foot" to allow conversion from RUX package to DIP (or SOiC or something).

Thanks!

    Hi Rick,

    Are you looking for something like TPS2121EVM?

    I don't believe we have any sockets or conversion boards, why do you need one?

    Thanks,

    Hi Patrick,

    I must do multiple environmental/parametric tests for at least 16 samples, so I desire an adapter board to use 1 PCB with multiple samples.  If I'm the first to request an adapter for the VQFN14-HR 12 (Ti's RUX package), I'm quite surprised!

    The TPS2121EVM is limited in limited quantity allowed to be purchased:

    2 /person /month at Mouser,

    5 /person at TI.com, and

    No stock at other distributors  (today Digikey has 1).

    7 < 16+ for what I need.  And I prefer to isolate the board(s) from the environments (expose the IC+adapter board only, as much as practical), even if I do use an eval board.

    Would you please confirm if there is an adapter board available from TI?  I'm not finding one available from my usual adapter board vendors.

    Thanks,

    Rick

    Hi Rick,

    Currently, TPS2121 is the only TI device that uses the RUX package, see here. My suspicion is that you may need to make a simple RUX breakout board - you should be able to put RUX footprint on one side connected to SOIC footprint on the other side. But let me see if we have anything that I'm not currently aware of, I will send you an update tomorrow.

    Thanks,

    Patrick

    Hi Rick,

    Unfortunately, we don't make or have any adapter boards. My recommendation is to put the RUX and footprint of your choice on opposite sides of a PCB and connect them internally.

    Apologies for increased effort this may cause.

    Thanks,

    Patrick

    Why does TI make parts with a new footprint/package and then do not support the package?

    Why ask why?

    Hi Rick,

    I apologize for the difficulties this causes, but we don't produce nor have any RUX adapter boards. TI has many, many packages, some of which are only used by one device, and we receive very few requests for adapter boards. My recommendation is to create a PCB adapter board with RUX/SOIC footprint, or to place a high-temp rubber barrier around the TPS2121 on the EVM to isolate the rest of the board from the elements, then use the same board for multiple tests.

    Thanks,

    Patrick
