1. When ordering, please specify packaging code:
FA2636-ALD
Packaging: 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.
2. Inductance is for the primary, measured at 250 kHz, 0.2 Vrms, 0 Adc.
3. Ipk is peak primary current drawn at minimum input voltage.
4. DCR for the secondary is per winding.
5. 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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

• 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
