For National Semiconductor

PoE Transformers LM5070 PoE Interface

These surface mount flyback transformers were devel-

opedspecificallyfortheNationalSemiconductorLM5070

Powered Devices Interface in 13 Watt Power over Eth-

ernet (PoE) applications.

They are designed to operate at 250 kHz with an input

voltage of 36 – 72 Volts. These industry-standard size

EP13 transformers feature 1500 Vrms isolation from the

primary and bias windings to the secondary.

Coilcraft can also custom design transformers with

voltage, inductance and DCR values to meet your spe-

cific requirements.
