For Texas Instruments TPS2375  
PoE Transformer PoE Powered Device Controller  
These synchronous flyback transformers are designed  
specifically for the Texas Instruments TPS2375 Pow-  
ered Device Controller for use in IEEE 802.3af-compli-  
ant 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.  
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. For free evaluation  
samples, contact Coilcraft or visit www.coilcraft.com.

1. Inductance is measured at 100 kHz, 0.1 Vrms.  
2. Peak primary current drawn at minimum input voltage.  
3. DCR for secondary is with windings connected in parallel.  
4. Leakage inductance is for the primary winding with the secondary windings shorted.  
5. Turns ratio is with both secondary windings connected in parallel.  
6. Operating temperature range –40°C to +125°C.  
7. Electrical specifications at 25°C.
