Introduction
The NCP1083 is a member of ON Semiconductors high power
HIPO Power over Ethernet Powered Device (PoEïPD) 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 PoEïPD interface supporting
the IEEE 802.3af and the 802.3at standard and a flexible and
configurable DCïDC converter controller.
The NCP1083s exceptional capabilities enable applications to
smoothly transition from nonïPoE 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 Semiconductors 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 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 PoEï 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, highïend V oIP phones, notebooks, etc.
The integrated current mode DCïDC controller facilitates
isolated and nonïisolated flyïback, 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 startïup.
The NCP1083 is fabricated in a robust high voltage
process and integrates a rugged vertical Nïchannel 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 Semiconductors ASSP
portfolio in industrial devices and can be combined with
stepper motor drivers, CAN bus drivers and other highï
voltage interfacing devices to offer complete solutions to the
industrial and security market.
