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.
