SI3406FB3V2-KIT: 7W POE, 3.3V @ 1.5A, 37 ~ 57V in

Summary

The Si3406 isolated Flyback evaluation board is a reference design for a power supply in a Power over Ethernet (PoE) Powered Device (PD) application.

This Si3406-Flyback EVB provides simple and low-cost solution with different output voltages and power levels.

The Si3406 IC integrates an IEEE 802.3at compatible PoE interface as well as a current control-based dc/dc converter.

The Si3406 PD integrates an internal rectifier bridge, detection circuit, classification circuit, dc/dc switch, hotswap switch, TVS overvoltage protection, dynamic soft-start circuit, cycle-by-cycle current limit, thermal shutdown, optional synchronous secondary rectification driver, automatic and user mode MPS generation, and inrush current protection.
