TIDA-050026-23882
用于多端口应用的 24 端口（PoE 2、2 线对）电源设备参考设计
TIDA-050026-23882
概述
This reference design showcases a Type-3, 30W, 2-Pair 24-port Ethernet switch for Power over Ethernet (PoE) applications which can send up to 30W per port for IEEE 802.3bt Type 3 applications and up to 60W per port for non-standard applications. Based on the MSP430F523x and MSPM0G1107x family, TI's TPS2388x FirmPSE system firmware provides a total system level solution for multi-port applications which reduces time to market and frees-up valuable software resources. This design supports port power management with priority, multiple power supplies, legacy PD detection, field upgradability, UART/I2C communication with the host, and more. TI’s FirmPSE system firmware GUI for this design enables the customization of production level PSE system firmware code with just a few clicks of a button and provides real-time communication to the system. In addition, two of these designs may be cascaded through the edge connectors in order to support up to 48-port PSE systems.
