TPS23754 in flyback mode for 1 Gig POE+ application

Other Parts Discussed in Thread: TPS23754, TPS23754EVM-383, TPS23754EVM-420

Hi,

We are planning to use TPS23754 in synchronous flyback mode for 1 Gig POE+ application.

In TPS23754EVM-420 ref schematic ,the ethernet interface is not for 1Gig but TPS23754EVM-383 for active clamp forward converter the ethernet interface is for 1Gig.

I want to know if we can use the TPS23754 in synchronous flyback mode for 1 Gig POE+ application.Are there any limitation for TPS23754 in synchronous flyback mode for 1 Gig application.

Please reply

Regards

Any POE, type 2 equipped ethernet transformer can be used with any TPS23754 based PD (and dc/dc converter topology). You can use the J3 jack from TPS23754EVM-383 with the PD on TPS23754EVM-420 for example. Other POE type 2 giga-bit transformer options are Wurth 749022011 or Pulse H6096NL.

Hi Eric,

Thanks for the reply .So you mean that we can use TPS23754 in fly back topology for 1Gig application only thing that need to be taken care is the TYpe 2 giga- bit transformer.
