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 = 13machine 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.
