Part Number: TPS23753A Other Parts Discussed in Thread: PMP8803 , PMP20531 Tool/software: Hi, TI expert
A customer is considering TPS23753A to apply PoE PD solution to Network Decorder.
- Input : 1000BASE(gigabit)
- Output : 12Vdc
Is it possible…
Hi Austen,
For the option 2 ORing, I would suggest to use TPS23753A or TPS23758. Since TPS23755 doesn't have an APD pin. Once the VDD is lower than the UVLO voltage (typically 37V) the PD chip will be shut down.
TPS23753A or TPS23758 has an APD pin…
Hello,
I reviewed the schematic and here are my comments:
- I do not think you need R4783
- I could not find the FET datasheet, but ensure VDS does not exceed the FET voltage rating
A great resource for designing with the TPS23753A with flybacks…
Hi Eric,
In order to be compliant, PoE should be 1-to-1 system for PSE and PD. So the block diagram should be like below.
For the PD design, I recommend using PMP20531 for both blocks.
For the PSE, I recommend TIDA-00465
Part Number: TPS2375 Other Parts Discussed in Thread: PMP20531 , PMP30290 , TPS2373-4EVM-758 Hi, the PMP5595 reference design seems have the ideal characteristics to power our PoE application. I am noticing in the schematic that the the connections to…
