Dear sir/Madam,
I need to design the PoE PD module for the 12W application. I did the design using TPS2377-1.
I have doubt about the Mode A and mode B types of transmission in PoE communication.
How do I make the circuit compatible with Alternative A and Alternative B?
I know Mode B was widely used in small applications. But our client required that power module compatible with both modes(A&B)
and also I need the document for "how to select proper center tapped transformer for different types of PoE PD application".
