nt flyback transformers were developed specifically for the ST Microelectronics STE12PS 12-Channel PSE Power Control Device. They are designed to work with a 3.3 V input to provide a 12 V output. Isolation is 500 Vdc from each primary winding to the secondary winding. Coilcraft can also design custom transformers with voltage, inductance and DCR values to meet your specific requirements.
