Other Parts Discussed in Thread: TPS2376
At present, when our company uses your TI chip TPS2376DDAR-H, it is found that there is no output when using POE power supply, please help to support and deal with it.
This chip is used in two projects of our company, the POE power supply in project A is normal, and the POE power supply in project B is problematic, and there is no output
The output waveform through the rectifier bridge is as follows:
Item A, normal output, 53V
Item B, no output, unable to shake hands with the device.
On the schematic diagram, the circuit is consistent, and it has also tried to replace peripheral devices, transformers, RJ45, TPS2376 POE chips, rectifier Bridges, etc., without effect
