NCP1081DER2G

POE, CTLR, 40W, 20TSSOP.

The NCP1081DER2G is an integrated high power PoE-PD Interface and DC to DC Converter Controller offers new opportunities for the design of products powered directly over Ethernet lines, eliminating the need for local power adaptors or power supplies and drastically reducing the overall installation and maintenance cost. ON Semiconductor's unique manufacturing process and design enhancements allow the NCP1081 to deliver up to 25.5W for the draft IEEE802.3at (D3.0) standard and up to 40W for proprietary high power PoE applications. It enables the draft IEEE802.3at (D3.0) and implements a two event physical layer classification. Additional proprietary classification procedures support high power sourcing equipment (PSE) on the market. The unique high power features leverage the significant cost advantages of PoE-enabled systems to a much broader spectrum of products in emerging markets.
