Looking at the schematic, the circuit was designed on PMP7355 PCB. It's gerber files on the PMP7355 product page below.
Layout guidelines are described in SLUA469 for optimum PoE performance.
If using the POE13F-50L, does this mean you are designing with a diode on the secondary? I recommend looking at PMP7355 as a reference when using this transformer with the TPS23753A. There are not too many differences and mostly only component…
The TPS23758 EVM uses primary side regulation (PSR). This feature eliminates the need for a optocoupler + feedback network, but requires an additional winding on the transformer for the regulation. We have tested the Linkcomm transformer…
