NCP1083DEG

NCP1083 belongs to ON Semiconductor's high-power HIPO Power over Ethernet devices (PoE-PD) family of products, is a rugged, flexible and highly integrated solution for demanding medium and high power Ethernet applications. It combines an enhanced PoE-PD interface that is fully compliant with the IEEE D3.0 specification and the upcoming IEEE 802.3at (D3.0) draft specification with a flexible and configurable DC-DC converter controller in a single device. network, thus eliminating the need for an auxiliary switching power supply. ON Semiconductor's unique manufacturing process and design enhancements enable the NCP1083 to provide power supplies up to 25.5 W in compliance with the IEEE 802.3at (D3.0) draft standard and up to 40 W for exclusive high-power PoE applications. physical layer categories. Additional proprietary classification processes support the market for high power power supply equipment (PSE). These unique high-power capabilities bring the significant cost benefits of PoE-enabled systems to a wide range 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, laptops, and more. This integrated current-mode DC-DC controller enables isolated and non-isolated flyback, forward and buck converter topologies. It has all the features needed for a flexible, rugged, and energy-efficient design, including programmable switching frequency, duty cycle up to 80%, ramp compensation, and soft-start. manufactured using a rugged, high-voltage process, the NCP1083 integrates a rugged vertical N-channel DMOS with low-loss current-sensing technology for the most demanding environments.
