These isolated synchronous flyback transformers are developed specifically for Texas Instruments PMP929reference design. They are designed to be used with the TI TPS2375 Powered Device Controller in IEEE 802.3af-compliant applications.

They are designed to operate up to 500 kHz with input voltage between 18 and 72 Volts. Output of the bias winding is 10 V, 20 mA and output of the drive winding is 5.6 V 10 mA.

Each transformer features interleaved primary and sec-ondary windings to minimize leakage inductance, and separate bias and drive windings. Isolation is 1500 Vrms between the primary and the secondary windings.Coilcraft can also custom engineer a transformer to meet your specific requirements.

1.When ordering, please specify packaging code:

C1174-AL D

Packaging:D =13″ machine ready reel. EIA-481 embossed plastic

tape (200 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 measured at 100 kHz, 0.1 Vrms.

3.Peak primary current drawn at minimum input voltage.

4.DCR for secondary is with windings connected in parallel.

5.

Leakage inductance for the primary is with the secondary and drive

windings shorted; leakage inductance for the drive is with the secondary windings shorted.

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

7.Operating temperature range –40°C to +125°C.

8.Electrical specifications at 25°C.
