Part Number: TPS2375EVM Hi Support,
Please advise whether the output of the EVM is AC or DC and what the voltage is.
The user guide only mentioned 48V supply.
Want to know if this 48V will change if the PSE side changes.
Please confirm.
Thanks…
Part Number: TPS23880 Other Parts Discussed in Thread: TPS2375EVM We are using the TPS23880 in automatic mode and although it correctly classifies various PD loads we are getting the ports turning off before it reaches the appropriate limits, specifically…
Part Number: TPS2378 Other Parts Discussed in Thread: TPS2375EVM , I am attempting to use PoE to power my design (board powered by DCDC needing power from PoE) but the PD power shuts down when I connect the power out from the TPS2378EVM-105 to my design…
Hi Sibi,
The ground of VSS and RTN cannot be shared. Besides, the PG pin is usually needed, since the PD itself has inrush delay, and the PG will be set low during inrush. Please find a typical structure for TPS2375 in below.
You can refer the TPS2375…
Hi AQ,
Can you described what the signals are on each of your channels? If CH1 is Vout, are you designing for 57Vout?
Did you say your design is based on TPS2376HEVM or TPS2375EVM? Could you post a schematic to show the changes you made?
Thanks…
Thank you very much! We are going to review the TPS2375EVM to use the exact same parts. In case it does not resolve the problem, maybe we can try using the TPS2378 model.
Regards,
Pablo.
Hi Gergely,
It sounds like the PoE functionality is working as the power is being delivered to the MCU after successful detection and classification? Is the MCU being powered by PoE via DCDC converter? Is the converter stable? The power and data should…
