High-Frequency Wirewound Flyback Transformers - PA

Pulse Electronics Power's high-frequency wirewound flyback topology transformers are ideally suited for 1.8 W low-power discontinuous mode isolated designs where 3.3 V, 5 V, and 12 V are needed to be converted from 24 V or 48 VBUS architectures. The PA4470 series transformers provide 1,650 VDC isolation voltage to sensitive circuits. The applications for these transformers are POE, industrial control, SMPS, and motor control.
