TPS2373: Select solution

Part Number: TPS2373

Dear team

The spec of customer's application is need 802.3bt Type 4 class8 and PSR mode.

Is there suitable solution for this requirement?

Many thanks


  • Hello Denny, 

    At this time, we do not have a reference design that is Type 4 power and uses primary side regulation. We do have some Class 6, 51W solutions, but I know that is not enough power.

    I can say it is possible to do, all you would need is a suitable transformer. You would need to work with a transformer vendor to define the transformer. But you could use the TPS23731 EVM and ask them to make a 71W version. Obviously it will be bigger, but it could be done. 

    We do have Type 4 Class 8 solutions if you can manage without PSR?

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