For 3 Watt, 7 Watt and 13 Watt

Flyback Transformers PoE Applications

• Flyback transformers for PoE applications

• Designed to operate in continuous mode at 250 kHz with

an input of 36 – 72 Vdc

• 1500 Vrms isolation from primary and bias to secondary

Designer’s Kit C395 contains two of each part shown in bold

Core material Ferrite

Terminations RoHS tin-silver over tin over nickel over phos

bronze. Other terminations available at additional cost.

2. Inductance is for the primary, measured at 250 kHz, 0.1 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 4 with all other pins

shorted.

6. Turns ratio is with the secondary windings connected in parallel.

7. Output of the secondary is with the windings connected in parallel. Bias

winding output is 12 V, 20 mA.
