Supporting communications, industrial, and consumer applications, ON Semiconductor’s NCP1081 and NCP1083 integrated Power-over-Ethernet Powered Device (PoE-PD)/DC/DC converter controllers have been verified to meet the upcoming IEEE802.3at standard. The pin-compatible components provide power levels of up to 25.5 W for applications in line with the draft IEEE 802.3at (D3.1) standard and up to 40 W for proprietary high-power PoE applications. The units operate in a temperature range from -40°C to 85°C with full operation up to 150°C junction temperature. The devices have also been verified by the University of New Hampshire Interoperability Laboratory (UNH-IOL) for the recent draft IEEE 802.3at (D3.1) standard. Pricing is $1.80 and $1.85, respectively, each in 1,000 quantities and above.
