High Efficiency PSE Controller Addresses New IEEE 802.3at PoE+ Standard
MILPITAS, CA – November 11, 2009 – Linear Technology Corporation introduces the LTC4274, a single-channel Power over Ethernet (PoE) controller for power sourcing equipment (PSE) required to provide IEEE 802.3at (25.5W) or proprietary higher power levels. Next-generation PoE applications call for more power to support demanding features, while increasing power efficiency in an effort to be more “green” and reduce costs. The LTC4274 provides up to 100W over 4-pair Ethernet cabling and is fully compliant with the new IEEE 802.3at PoE+ standard and backward compatible with the prior IEEE 802.3af PoE standard. To help conserve power, the LTC4274 delivers the lowest-in-industry heat … Read More → "High Efficiency PSE Controller Addresses New IEEE 802.3at PoE+ Standard"
