Si3404 Powered Device Isolated Class 3 Evaluation Kit
With decades of high-voltage design expertise and a proven track record of supplying hundreds of millions of high voltage products, Silicon Labs is enabling customers to integrate PoE into a wide array of products at the lowest overall cost and lowest design effort with the Si3404 Powered Device (PD). Taking its cue from the world’s most highly integrated PD the Si3402, the Si3404 now also breaks new ground by reducing the package footprint to a mere 4x4 millimeter QFN, taking pole position as both the world’s most-integrated and smallest full-solution PoE Powered Device IC. The Si3404 makes it simple and cost-effective for customers to add PoE capability to any Ethernet powered device application. By removing cost and design challenges, Silicon Labs is enabling widespread proliferation of PoE into the massive worldwide Ethernet infrastructure. PD Evaluation Kits are available as either non-isolated or isolated topologies. Generally, isolated topologies are chosen when there are non-Ethernet jacks also included in the power device equipment, such as AC/DC adapters, USB ports, RS-232 ports, etc. Isolated topologies provide the PoE subsystem protection from undesirable earth ground connections and provide users of the equipment a basic level of safety from electrical shock. The Si3404ISOC3-KIT contains an evaluation board with RJ-45 jacks to allow direct connection into a PoE-enabled system, as well as power supply connectors to enable monitoring of the Si3402’s regulated dc output. The board features a transformer-based isolation barrier with an isolated feedback loop, and is configured for Class 3 (15W and below) power.
