PoE++ PD controllers provide 90 W

摘要

The LT4275 powered-device (PD) interface controllers are LTP0E++-. P0E+-, and PoE-compliant and target applications requiring up to 90 W. The existing PoE+ standard limits the maximum PD power delivery to 25.5 W, which is insufficient for pi-cocells, base stations, signage, and heated outdoor cameras. The device expands the power budget to 38.7-, 52.7-, 70-, and 90-W power levels to accommodate these applications. They deliver power to PD loads using just one IC.
