Description

  • MAXREFDES1149, Reference Design for the 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. The MAXREFDES1149 reference design is a 36V to 57V input to 12V/1A output flyback PoE PD power module to be used in Ethernet equipment that needs the 12V power supply to be isolated from the primary Ethernet 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
