NCP1082

NCP1082 Integrated PoE-PD & DC-DC Converter Controller with 9 V Auxiliary Supply Support Introduction The NCP1082 is a member of ON Semiconductor’s Power over Ethernet Powered Device (PoE−PD) product family and represents a robust, flexible and highly integrated solution targeting demanding Ethernet applications. It combines in a single unit an enhanced PoE−PD interface fully supporting the IEEE 802.3af specification and a flexible and configurable DC−DC converter controller. The NCP1082’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 NCP1082 to deliver up to 13 W of regulated power to support PoE applications according to the IEEE 802.3af standard. This device leverages the sig...
