ON Semiconductor – Down to the Wire: PoE Converter and Controller Solutions


OnSemi-logo NPI_LOGO
Quite often we tend to primarily interact with electronic devices in a mobile or stationary state. Security cameras, controlled lighting, intercoms, and badge card entry scanners are all examples of devices that are removed from ample infrastructure but are not mobile. These remote devices need both power and data communication lines. In the last decade, Power Over Ethernet (PoE) has become a system that resolves the need for multiple connections. PoE is system that can safely and effectively transfer both power and data over a standard twisted pair cable within an Ethernet network. This standardized technology increases network device compatibility, ease of device deployment, device life cycle savings, system reliability, and safety.

ON Semiconductor offers a product family that represents a robust, flexible, and highly integrated solution. This IEEE compliant family is a flexible system that can be used as configurable DC-DC converters and controllers. Along with exceptional capabilities that enable applications to smoothly transition from non-PoE to PoE enabled networks, ON Semiconductor has also integrated this device into a shield for use with the modular IoT Development Kit. ON Semiconductor now offers industry leading solutions for all of your mobile, stationary, and remote devices.
