For National Semiconductor  
Flyback Transformer LM5020 PWM Controller  
• Designed to operate up to 1 MHz with 36 –72 V input.  
• 3.3 V, 4.5 A output with secondary windings connected in  
parallel. Bias output is 12 V.  
• Ideal for 13 W, IEEE 802.3af-compliant, PoE applications.  
Core material Ferrite  
Terminations RoHS tin-silver over tin over nickel over phos  
bronze. Other terminations available at additional cost.  
Weight 12.8 g  
Ambient temperature –40°C to +85°C  
Storage temperature Component: –40°C to +85°C.  
Packaging: –40°C to +80°C  
Resistance to soldering heat Max three 40 second reflows at  
+260°C, parts cooled to room temperature between cycles  
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /  
85% relative humidity)  
Failures in Time (FIT) / Mean Time Between Failures (MTBF)  
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332  
Packaging 175 per 13reel Plastic tape: 44 mm wide,  
0.4 mm thick, 32 mm pocket spacing, 11.9 mm pocket depth

1. When ordering, please specify a packaging code:  
B0695-ALD  
3. Ipk is the peak current drawn at minimum input voltage.  
4. DCR for the secondary is per winding.  
5. Leakage inductance measured between pins 4 and 6 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 bias to the secondary.  
9. Electrical specifications at 25°C.  
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.  
2. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
