Flyback Transformer Document 1139 Document 1139 Revised 08/08/13 For Texas Instruments TPS23753A PoE controller Leakage Part L at 0A2 L at Ipk3 DCR max (Ohms)4 inductance Turns ratio6 number1 ±10% (µH) min (µH) pri sec bias sync max (µH)5 pri : sec pri : bias pri : sync Output7 1. When ordering, please specify packaging code: NA6223-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 1 kHz, 0.5 Vrms, 0 Adc. 3. Peak primary current (1.1 A) drawn at minimum input voltage. 4. DCR for the primary is from pin 1 to pin 2. 5. Leakage inductance measured between pins 1 and 2 with all other windings shorted. 6. Turns ratio is with the primary windings connected in series. 7. Output is between pins 7 and 10. Bias winding output is 10 V, 20 mA. Sync winding output is a 5 V Sync FET gate drive signal. 8. Electrical specifications at 25°C.
