Tool/software:
It's an urgent case from Delta.
We would like TPS23730 to support adaptor 24~48V. How to modify TPS23730EVM-093 schematic to support this adaptor range? What is the new transformer spec like?
We like to disable POE while adaptor appliing and adaptor is first priority.

Frank
Hi Frank,
Thanks for reaching out. I worked with Barton Tung on a flyback using 24 - 48V adapter which could be related to the same Delta project. This used option 2 of Advanced Adapter ORing Solutions using the TPS23753 (Rev. A PoE PD will be disabled when adapter is connected and APD pin is high.
Please let me know if you are asking a different case.
Best regards,
Diang
Hi Diang,
Thanks for your help. It's the same project. Since E2E is an public forum, I cannot post my schematic here. Btw, we prefer flyback+option2, it's simple and seems robust to surge.

Hi Frank,
Thanks for your information. I have checked the schematic with Barton and it uses Option2. Hope you and he have got aligned.
I will close this thread for now.
