説明
- MAXREFDES1009, Power over Ethernet (PoE) is a technology that allows network cables to deliver power to a powered device (PD) via power-sourcing equipment (PSE) or midspan and has many advantages over traditional methods of delivering power. PoE allows power and data to be combined, removing the need for altering the AC mains infrastructure and can be installed by non-electricians. PoE is an intelligent system designed with protection at the forefront, preventing overload, underpowering and installation errors, while allowing simple scalability and reliability. High-efficiency, step-down switching regulators minimize power loss with efficiencies greater than 90%, allowing reductions in excessive heat, longer lifetime of ICs and maximum power available to the PD
