The NCP1081 and NCP1083 integrated POE powered device, dc/dc converter controllers have been verified to meet the upcoming IEEE802.3at standard for high power communications applications. They provide power levels up to 25.5 W 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. Low on-resistance (Ron) and extended temperature range from –40° to 85°C with full operation up to 150°C junction temperature allow these controllers to operate in harsh environments. (Ea/1,000: NCP1080, $1.45; NCP1081, $1.80; NCP1082, $1.48; NCP1083, $1.85 — available now.)
