The NCP1083 is a member of the ON Semiconductor high power HIPO™ Power over Ethernet Powered Device (PoE-PD) product family and represents a robust, flexible and highly integrated solution targeting demanding medium and high power Ethernet applications. It combines in a single unit an enhanced PoE-PD interface supporting the IEEE 802.3af and the upcoming draft IEEE 802.3at (D3.0) standard and a flexible and configurable DC-DC converter controller.
The NCP1083's exceptional capabilities enable applications to smoothly transition from non-PoE to PoE enabled networks by also supporting power from auxiliary sources such as AC power adapters and battery supplies, eliminating the need for a second switching power supply.
ON Semiconductor's unique manufacturing process and design enhancements allow the NCP1083 to deliver up to 25.5 W for the draft IEEE 802.3at (D3.0) standard and up to 40 W for proprietary high power PoE applications. The NCP1083 enables the draft IEEE 802.3at (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 such as industrial ethernet devices, PTZ and Dome IP cameras, RFID readers, MIMO WLAN access points, high-end VoIP phones, notebooks, etc.
The integrated current mode DC-DC controller facilitates isolated and non-isolated fly-back, forward and buck converter topologies. It has all the features necessary for a flexible, robust and highly efficient design including programmable switching frequency, duty cycle up to 80 percent, slope compensation, and soft start-up.
The NCP1083 is fabricated in a robust high voltage process and integrates a rugged vertical N-channel DMOS with a low loss current sense technique suitable for the most demanding environments
Features   Benefits
     
  • Auxiliary supply support with an input down to 9 V DC in combination with an extended power range up to 40 W.
 
  • Eliminates the need for a second DC-DC converter to support traditional non-PoE power sources which may range down to 9 V.
  • Improved robustness behavior against cable ESD. The NCP1083 reaches more then 4 kV on HBM and 3 kV for CESD.
 
  • Protects the device against cable transients and hot swap events that can occur in harsh environments and when installed outdoors.
  • A programmable operational current limit up to 1100 mA for extended power ranges up to 40 W.
 
  • Supports the IEEE802.3at and proprietary high power solutions beyond the standard up to 40 W.
