TPS23758EVM-080: TPS23758

Part Number: TPS23758EVM-080
Other Parts Discussed in Thread: TPS23758

Tool/software:

Hi TI,

We have space constraints in the design and hence prefer the EP7 type transformer (XFMR) over EP13. Is it possible to design for 5V 13W with an EP7 XFMR type and an auxiliary power input of 9V to 24V using the TPS23758? Please share the required modifications in the circuit for the TPS23758EVM-080.

Regards,

Harsha

  • Hi Harsha,

    Thanks for reaching out! Sorry that PoE team is quite busy recently. I will try to get back to you by this week.

  • Hi Harsha,

    For off the shelf products EP7 normally only support Class2 (6.5W) or lower power as flyback transformer. Normally its power rating is less than 8W.

    May I know what is your target dimension? We used to work with costumed transformer vendor can do ~11x11x14mm, 14m is height, for 25.5W applications. I can help you to connect some transformer vendors if you want. 

    Best regards,
