Part Number: TPS23758

Hello,

I'm designing a PoE+ (13W) device for which I need an insulation of 3-4kV instead the usual 1500V.

Does TI have an Application Notes or White Papers related to the problem above?

Thanks for any suggestion.

Hello,

Please see the following app note on Surge protection: Lightning Surge Considerations for PoE Powered Devices

The 1500V is typically driven by the transformer. TI does not make transformers, so you will need to work with your magnetics vendor for this. Thanks.

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