Simple, Efficient, and EMI Compliant Power Over Ethernet EVBs
The latest PoE designs from Skyworks use Würth Elektronik transformers to simplify designing, testing, and procuring magnetic components
With Skyworks Solutions' latest PoE evaluation boards, which leverage Würth Elektronik's standard PoE transformers to simplify sourcing magnetic components, users can easily add 15 W, class 3 Power over Ethernet (PoE) to any design. The three isolated flyback designs offer 3.3 V, 5 V, and 12 V output options, all reaching over 80% peak end-to-end (PoE input to DC output) efficiency. All three use a simple four-layer PCB and are fully EMI compliant with the EMI report included in the user guide. Skyworks' Si3404 PoE PD device manages both the IEEE PoE interface and the DC/DC conversion with internal FETs to reduce board space and costs.
