Flyback power transformer gives enhanced DC-DC power conversion efficiency
Created to support IEEE 802.3 af-compliant, Bourns' integrated PoE PD and PWM controller applications, model SM13117EL gives DC-DC power conversion in isolated mode.
Created to support IEEE 802.3 af-compliant, Bourns’ integrated PoE PD and PWM controller applications, model SM13117EL gives DC-DC power conversion in isolated mode.
The device flyback transformer features 13W of output power, 36-72 VDC / 250 kHz input, 12 VDC / 1.08 A output and 1.5 kVrms withstanding voltage. This low profile, small form factor PoE flyback transformer also provides an extended -40°C to +125°C operating temperature range, low leakage inductance and outstanding 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 provides the UL 94 V-0 flammability rating.
The features of the company’s latest flyback power transformer make it an attractive power conversion solution for a wide range of PoE-powered devices incorporating VoIP phones, WLAN access points and network cameras as well as with integrated PoE PD interface and PWM controllers provided by several leading IC manufacturers.
