ON Semiconductor 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 for high power communications applications.

Both devices have also been verified by the University of New Hampshire Interoperability Laboratory (UNH-IOL) for the upcoming IEEE 802.3at (D3.1) standard, which includes a test of the two event physical layer classification.

The UNH tests confirm these devices can enable PoE+ compliant platforms on the market, and are in line with the evolving high power requirements of the WLan access point, WIMax, industrial and IP camera markets.

ON Semiconductor’s portfolio of integrated PoE-PD products contains four devices. The NCP1081 and NCP1083 provide power levels up to 25.5 watts (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 NCP1080 and NCP1082 offer IEEE802.3af compliant power levels. The NCP1082 and NCP1083 are also capable of providing power via an auxiliary parallel supply.

The NCP1080/1/2/3 are pin-compatible and offered in a TSSOP-EP 20 pin package. This feature allows the customer to easily mix-and-match different PoE capabilities on different platforms.

The PoE-PD portfolio uses ON Semiconductor’s automotive qualified, high-voltage SmartPower process to provide superior cable electrostatic discharge (CESD) and surge protection levels compared to other integrated PoE-PD /DC-DC converter controllers.

Low on-resistance (Ron) and extended temperature range from -40°C to 85°C with full operation up to 150°C junction temperature allows these PoE-PD controllers to achieve record power levels while operating in harsh environments.

All NCP1081/2/3/4 devices are currently available. The per unit prices for quantities of 1,000 and above are $1.45 for the NCP1080, $1.48 for the NCP1082, $1.80 for the NCP1081, and $1.85 for the NCP1083. NCP1081/3 evaluation boards are available for $150.
