Good evening everyone,
I have to choose the your best integrated circuit to create a PoE++ splitter, with very high output power; approximately 70 - 90 Watts with an output voltage that I will adjust to approximately 30 - 35 Volts,
with a current of approximately 2 to 3 amps (or the maximum possible).
I think that the your best IC Now is the LT4295; it have all the standard IEEE 802.3af/at/bt Powered Device (PD) with Forward/Flyback Controller, and all the functions integrated.
I'm evaluatin also The LT4276 that is almost powerfull. And High power module like LT4293 -> but i don't know if this model are complete ?? and what is "Isolated Power Supply" this last model need another isolated switchin for the Vout ???
Ultimately what is the best choice to build the best PoE++ Splitter PD Now ???
Thank you very much
