Hi team,
I'm using a TPS23750 non-isolated, class 0, 5V - 2A
When I connect a first product to a professional POE switch (D-Link or Dell) , everything is always OK, but, when I connect a second product, the fist POE step - Basic Detection - always fails using a shielded patch cable.
There isn't any trouble using a non-shielded patch cable: I connected up to 6 products, everything is OK.
I would like to keep a non-isolated solution (efficiency, cost, size, time).
What can I do to achieve it?
Best regards,
Olivier Dufour
