For National Semiconductor

PoE Transformer LM5070 PoE Interface

This surface mount flyback transformer was developed

specifically for the National Semiconductor LM5070

Powered Devices Interface in 13 Watt Power over

Ethernet (PoE) applications.

It is designed to operate at frequencies up to 1 MHz

with an with an input voltage of 36 – 72 Volts. Output

with the secondary windings connected in parallel is

3.3 V, 4.5 A. Isolation is 1500 Vrms from the primary

and auxiliary windings to the secondary.

Coilcraft can design custom transformers with volt-

age, inductance and DCR values to meet your specific

requirements.

For free evaluation samples, contact Coilcraft or order

them on-line at www.coilcraft.com.

1. When ordering, please specify a packaging code:

C1023-ALD

3. Ipk is the peak current drawn at minimum input voltage.

4. DCR for the secondary is per winding.

5. Leakage inductance is for the primary winding with all other pins

shorted.

6. Turns ratio is with the secondary windings connected in parallel.

7. Capacitance measured between pins 3 and 4 with other pins shorted.

8. Isolation is measured from the primary and aux to the secondary.

Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic

tape (175 per full reel).

B = Less than full reel. In tape, but not machine ready. To

have a leader and trailer added ($25 charge), use

code letter D instead.

9. Operating temperature range

–40°C to +85°C.

2. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.

10. Electrical specifications at 25°C.
