Part Number: TPS23755
Other Parts Discussed in Thread: TPS23758

Dear Sir,

I saw TPS23755 datasheet page-31, Fig-39 have a buck application circuit.

My customer would use this circuit to design a 5V/12W PoE solution.

Could you kindly help provide a complete reference design(include component value).

Does this have design tools?

Thanks!

Hi Steven,

TPS23755 can't be designed in 5V/13W design but it can be designed in Class2 power level. If customer is interested in Class 2 design, we can send schematic offline. For a 13W design, I recommend the TPS23758.

Please let me know if having any additional questions and thank you for considering Texas Instruments PoE products.

Best Regards,

Sean Liao
