K2E Evaluation Board, Part TPS544C24

Kerry LaFond

Other Parts Discussed in Thread: AM5K2E04, TPS544C20, TPS544C25, TPS65400

I am working on a hardware design that includes the AM5K2E04. I was using the K2E_EVM evaluation board as a guide and was looking up a part that is shown on both the Schematic and BOM for the K2E_EVM (TI P/N TPS544C24)

I am unable find a data sheet for TI part number TPS544C24, but was able to find part number TPS544C20 which has the same pin out as the part shown in the K2E_EVM schematic.

Can someone enlighten me as to whether the TPS544C24 is available, and/or if the TPS544C20 is an acceptable replacement?

Thanks,

Kerry

Hello Kerry,

The TPS544C24 part is not available in the TI port folio. I am not sure, this is typo in schematics and BOM or the part is under evaluation internally. I will check with the concern team and get back.

Meanwhile, you can proceed on your design having TPS544C20 in place of TPS544C24 as this is pin to pin compatible and its rating also meets the requirement.

Regards,

Senthil

I came across another part in the K2E_EVM schematic and BOM that appears to be unavailable also: LM26430. Is there a recommended replacement for this?

Kerry,

The TPS544C20 may be pin compatible but it is not functionally identical to the TPS544C24.

The TPS544C24 is being replaced by the TPS544C25. The TPS544C25 will be sampling in 1Q15. Please contact your TSR or FAE to get the pre-release datasheet. Samples of the TPS544C24 can be requested and used for prototyping. The TPS544C24 and TPS544C25 are functionally identical.

The LM26430 has been renamed as the TPS65400. A product page is available for this new part number.

The latest version of the K2E EVM schematic shows these corrected part numbers. It has not been released to the web yet. It will be soon. Once it does you can find it at: https://www.einfochips.com/index.php/partnerships/texas-instruments/k2e-evm.html#5-resources.

Can you tell if TPS544C25RVFT is available to order or not.

I have not heard if these are open for ordering yet. Plerase contact your AFAE or TSR. If not, they should be available soon.
