Part Number: TPS2373 Tool/software: Hi Team,
We are developing a traffic monitoring camera and which uses a POE++(60W) design as power input.
But when we are powering the device we are unable to see any class detection cycle in the VDD rails respect…
Hi Pavan,
Thanks for your patience.
If you want to test TPS2373-4 without UCC2897, you need to add a voltage source to VC_IN. Also, you need to DNP D3201 for the test. If no VC_IN input higher than UVLO, TPS2373-4 will have start up failure and go into…
Hi Mike,
Thanks for your patience.
It looks like the circuit goes into hiccup mode due to AC forward circuit overload .
Though the TPS2373-4's VC_IN and VC_OUT caps are corrected now, you may still need to open a new ticket to check with UCC2897A's engineer…
Part Number: TPS2373-4EVM-758 Tool/software: Hi,
Good day.
I am currently designing a POE product with TPS2373-4+UCC2897ARGPR and encountered a lack of space to place the electrolytic capacitor.
So, could you please guide me in determining the minimum…
Hi Diang,
I think I found the problem. TVS Diodes D2, D3, and D4 are listed as bi-directional in the BOM. Therefore, I didn't consider polarity when debugging. Unfortunately, our procurement team purchased unidirectional tvs diodes. D2 and D3 have the…
Hi,
Usually this type of debugging is to disconnect UCC2897A from TPS2373 then use an external bias voltage to UCC2897A VDD pin with the bias voltage 14V. Please do this then to find if UCC2897A converter normal and if it is normal then the issue is not…
Part Number: TPS2372 Other Parts Discussed in Thread: TPS2373 , Tool/software: Hello,
My customer wants to know the difference between TPS2372 and TPS2373. Could you please tell us the difference between the two products?
Thank you.
