Flyback transformers handle IEEE 802.3 af-compliant PoE PD and PWM controller apps

Bourns, Inc. announced an addition to the company’s flyback power transformer line. Designed to support IEEE 802.3 af-compliant, integrated Power-over-Ethernet (PoE) Powered Device (PD) and Pulse Width Modulation (PWM) controller applications, Bourns Model SM13117EL provides DC/DC power conversion in isolated mode.

The SM13117EL flyback transformer features 13 watts of output power, 36 – 72 VDC/ 250 kHz input, 12 VDC/1.08 amp output and 1.5k Vrms withstanding voltage. This low profile, small form factor PoE flyback transformer also offers an extended -40 to +125 °C operating temperature range, low leakage inductance and excellent EMI performance. Ensuring safe operation, the electrical insulation of the transformer complies with the UL 1446 Class B (130 °C) Insulation System. The transformer bobbin carries the UL 94 V-0 flammability rating.

The features of Bourns’ latest flyback power transformer make it an excellent power conversion solution for a broad range of PoE-powered devices including VoIP phones, WLAN access points and network cameras as well as with integrated PoE PD interface and PWM controllers offered by several leading IC manufacturers.

Bourns Model SM13117EL flyback power transformer is available now and is RoHS compliant.
