PoE PSE Type 2 (30W) IEEE 802.3at Fully Autonomous Quad Port Solution.

This reference design is fully autonomous IEEE802.3at: Type-2 (30 W) Power-over-Ethernet (PoE) 4-port power sourcing equipment (PSE). An additional configuration of two non-standard: high-power ports (This reference design is made up of two boards:Motherboard (TPS23861EVM-612)Daughter board (TPS23861EVM-613)The daughter board features two TPS23861 IEEE 802.3at PoE PSE controller devices. The motherboard provides a multi-port base platform interface for the daughter board. Additionally: the motherboard provides interfaces for two optional boards: MSP-EXP430G2 LaunchPad™ (if custom power management programmability is desired) and USB-to-GPIO interface adapter (if PC GUI-based power management configuration is desired).This reference design has undergone exhaustive PoE testing and passes all industry-recognized conformance/interoperability test suites allowing customers to copy/paste the design without concern. The 2-layer PCB: daughter card: design delivers all of this on a low-cost platform.
