Document 594 Flyback Transformer For Texas Instruments LM5001 Switch Mode Regulator • Developed for the Texas Instruments LM5001 High Voltage Switch Mode regulator for isolated and non-isolated flyback topologies. • Output of the auxiliary winding is 7.5 V used to power the IC • 1500 Vrms, one minute isolation from the primary and auxiliary winding to the secondary Core material Ferrite Terminations RoHS tin-silver over tin over nickel over phos bronze. Weight 6.28 g Ambient temperature –40°C to +85°C Storage temperature Component: –40°C to +85°C. Tape and reel 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 13″ reel Plastic tape: 32 mm wide, 0.5 mm thick, 32 mm pocket spacing, 12.98 mm pocket depth PCB washing Only pure water or alcohol recommended Inductance Part at 0 A2 number1 ±10% (µH) FA2636-AL_ 160 Inductance at Ipk3 min (µH) 144 Leakage DCR max (Ohms)4 Turns ratio6 inductance pri bias sec max (µH)5 pri : sec pri : aux 0.225 0.340 0.078 1.60 8:2 8:3 1. When ordering, please specify packaging code: Packaging: FA2636-ALD D = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 parts 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. Inductance is for the primary, measured at 250 kHz, 0.2 Vrms, 0 Adc. Ipk is peak primary current drawn at minimum input voltage. DCR for the secondary is per winding. Leakage inductance measured between pins 3 and 2 with all other pins shorted. 6. Turns ratio is with the secondary windings connected in parallel. 7. Operating temperature range –40°C to +85°C. 8. Electrical specifications at 25°C.
