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 is: …
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 the…
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
