NCP1081
Integrated High Power
PoE-PD Interface & DC-DC
Converter Controller
Introduction
The NCP1081 is a member of ON Semiconductors high power
HIPO Power over Ethernet Powered Device (PoEPD) 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 PoEPD interface supporting
the IEEE802.3af and the 802.3at standard and a flexible and
configurable DCDC converter controller.
The NCP1081s exceptional capabilities offer 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 Semiconductors unique manufacturing process and design
enhancements allow the NCP1081 to deliver up to 25.5 W for the
IEEE802.3at standard and up to 40 W for proprietary high power PoE
applications. The NCP1081 enables the IEEE802.3at 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 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 DCDC controller facilitates isolated
and nonisolated flyback, 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 startup.
The NCP1081 is fabricated in a robust high voltage
process and integrates a rugged vertical Nchannel 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 NCP1081 complements ON Semiconductors 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.
