Silicon Laboratory Inc. Si34071 | Demoboard Si34071AC5V8KIT

Overview

TopologyLAN / POE
Input voltage41.1-57 V
Output 15 V / 14 A
IC revision0.4

Description

The Si34071 5 V Class 8 evaluation kit demonstrates a complete 71 W IEEE 802.3bt Power over Ethernet Powered Device system using our Si34071 PoE PD device. A single Si34071 manages the PoE interface and dc-dc conversion. The isolated forward converter outputs up to 14.2 A at 5 V for a total power of 71 W while using a small EPD13 size transformer. The Sifos IEEE compliance report, schematics, and layout are all found in the User’s Guide.

Features

  • Included devices:-Si34071-GM
  • 71 W, isolated forward converter-5 V, 14.2 A output-Up to 91.2 % end-to-end efficiency-Small, EPD13 size transformer
  • Second RJ45 jack to pass through Ethernet

Typical applications

  • Powered Device system
