The Si3406FBC3-KIT Non-Isolated Flyback evaluation board integrates an IEEE 802.03at compatible PoE interface as well as a current control based dc/dc converter. The Si3406 PD integrates two diode bridges, which can be used up to 200 mA input current, detection circuit, classification circuit, dc/dc switch, hot-swap switch, TVS overvoltage protection, dynamic soft-start circuit, cycle-by-cycle current limit, syncrhonous gate driver, maintain power signature (MPS), thermal shutdown and inrush current protection. The switching frequency of the converter is tunable by an external resistor.
Evaluation boards are shipped configured to produce 5 V output voltage but can be configured for different output voltages, such as 3.3 or 12 V, by changing resistor R14 and a few other components. The Si3406 includes integrated diode bridge for both CT and SP connection. The integrated diode bridge can be used up to 200 mA input current. Above 200 mA input current the external diode bridge is required. The external diode bridge can be Schottky or silicon type. The Si3406 device can operate with CT/SP pins open, in this configuration the external bridge should be Schottky type diode bridge.
