Si34061 Isolated 5V Class 4 Evaluation Kit


The Si34061 5V Class 4 Evaluation Kit demonstrates a complete IEEE 802.3at Power over Ethernet PD system using Silicon Lab’s Si34061 PoE PD device. A single Si34061 manages the PoE interface and dc-dc conversion. The isolated flyback converter outputs up to 6A at 5V for a total power of 30W while using a small EPD13 size transformer. The Sifos IEEE compliance report, EMI test report, schematics, and layout, found in the User Guide, jump start new designs.
