Flyback Transformer
Document 914
Document 914 Revised 04/24/12
1. Inductance is measured at 50 kHz, 0.1 Vrms.
2. Peak primary current drawn at minimum input voltage.
3. DCR is with the primary windings connected in series and the secondary windings connected
in parallel.
4. Leakage inductance is for both windings of the primary with the secondary windings shorted.
5. Turns ratios are with the primary windings connected in series and the secondary windings
connected in parallel.
6. Output is with the secondary windings connected in parallel. Output of the aux winding is
15.5V V, 20 mA.
7. Electrical specifications at 25°C.
