Premier Magnetics Transformers Meet PoE, PoE+ and UPoE Power Specs

Premier Magnetics has introduced its expanded line of transformers designed to support the full range of Power-over-Ethernet (PoE) applications from IEEE 802.3af (15.4 W, max), IEEE 802.3at (30 W), Cisco UPoE and other higher-power PoE extensions up to 60 W. The low-profile, surface-mount devices operate over a wide frequency range, provide high isolation (1,500 V) and are available in forward and flyback topologies. These transformers are designed for use with power management integrated circuits (PMICs) from major manufacturers including Akros Silicon, Texas Instruments and Broadcom for application in both Power Sourcing Equipment (PSE) and PoE Powered Devices (PD). In addition, many of these parts are direct cross-reference with Pulse Electronics and CoilCraft devices.

Premier Magnetics PoE transformers are offered in two series: the EP Series (3W to 27W) and the EFD15 Series (1W to 60W). In addition to an extensive range of standard parts, custom designs are also available for each series.

The range of applications for PoE has dramatically expanded to include phones, remote video cameras and even large high-definition displays, said Jim Earley, president of Premier Magnetics. Our engineering expertise, responsive manufacturing and quality assurance program offer our customers the flexibility they need to bring new designs to market quickly.
