Hello, I'm using the TPS2372-4RGWR, and when I first plugged the ethernet cable (no loads), it made the whole process of detection, classification and power correctly. After that, I tried to connect 1 24V Led bar and it was okay, but when I tried to connect the third one, the power falls and it's not able to supply sufficient power.
Im using autocls in the TPS, and I have checked the possible differences between my schematic, and the schematic of the TPS2372-3EVM-757 board, which seems to be similar. Here is my PoE design, with a 24V regulator at the output of the TPS:
The TPS2372-3EVM-757 schematic is this:
The waveform I get when te power falls is the following:
After 130 ms, the power in the TPS falls.
Can anybody help me with this?
Thank you so much,
