Part Number: TPS2384
Other Parts Discussed in Thread: TPS2490, TIDA-00465, PMP20588

HI,

I wanted to know if the above circuit will function properly for a single port PoE standalone application?

Also, does it require a TPS2490 hot-swap controller ?

Hello,

We would recommend one of our single port PSE designs, but they use a newer part.

The TIDA-00465 uses a 54V DC input and an LDO to get the 3.3V rail.

The PMP20588 uses a 12VDC or 24V AC input which is then converted to 54V with a flyboost (like a flyback but the voltage is boosted).

I understand that there are ICs with single port standalone application. But most of them are out of stock. Can you please help in this design to make it stand alone?
