Part Number: TPS23754EVM-383
Other Parts Discussed in Thread: TPS23754EVM-420, TPS23754, TPS23734, TPS23734EVM-094

Dear Team

1. The customer would like to know, Whether TPS23754EVM-383 and TPS23754EVM-420 have been tested EMI(Electromagnetic Interference)?

Could you help to reply?

Many thanks

    Hey Denny, 

    These designs have not had EMI testing. The most important factor in EMI is the layout, and since that will always change in a design, we did not find it prudent to test EMI. That, as well as component selection, casing, and the load all contribute to EMI, so our results would not indicate anything meaningful to a customer unless they copied all of those choices. 

    I will say, the TPS23734 is the new generation of the TPS23754, and it has spread spectrum frequency dithering, which will improve EMI performance. 

    The TPS23734EVM-094 can directly replace TPS23754EVM-420. I would highly suggest moving to this new part for improved EMI performance. 

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
