Description
The NCP1083 is a member of ON Semiconductor’s 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 802.3at 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 IEEE 802.3at standard and up to 40 W for proprietary high power PoE applications. The NCP1083 enables the IEEE 802.3at and implements a two event physical layer classification. Additional proprietary classification procedures support high power power sourcing equipment (PSE) on the market. The unique high power features leverage the significant cost advantages of PoE− enabled systems to 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 and capable of withstanding harsh environments such as hot swap and cable ESD events.The NCP1083 complements ON Semiconductor’s ASSP portfolio in industrial devices and can be combined with stepper motor drivers, CAN bus drivers and other high− voltage interfacing devices to offer complete solutions to the industrial and security market
Features
- Auxiliary supply support with an input down to 9 V DC in combination with an extended power range up to 40 W.
- Improved robustness behavior against cable ESD. The NCP1083 reaches more then 4 kV on HBM and 3 kV for CESD.
- Improved robustness behavior against cable ESD. The NCP1083 reaches more then 4 kV on HBM and 3 kV for CESD.
- Eliminates the need for a second DC-DC converter to support traditional non-PoE power sources which may range down to 9 V.
- Protects the device against cable transients and hot swap events that can occur in harsh environments and when installed outdoors.
- Supports the IEEE802.3at and proprietary high power solutions beyond the standard up to 40 W.
Typical applications
- PoE in combination with a wall wart, Power over Ethernet Powered Devices (PoE-PD)
- Wall-wart alternative, IP PTZ cameras
