The LT4275AHMS#PBF is a powered device (PD) controller from Analog Devices Inc. (formerly Linear Technology) designed for IEEE 802.3af/at and LTPoE++ Power over Ethernet applications. This controller family supports various power levels, with the LT4275A variant capable of delivering up to 90W at the PD RJ45 connector through a proprietary LTPoE++ classification scheme. It is also fully compatible with IEEE 802.3 standards, offering up to 25.5W for PoE+ (802.3at Type 2) and up to 13W for PoE (802.3af Type 1).
The LT4275 features an internal charge pump for an N-channel MOSFET solution, enhancing power delivery efficiency and reducing thermal design complexity. Key integrated features include a power good output, on-board signature resistor, undervoltage lockout, and thermal protection. It supports pin-selectable non-standard low voltage operation and auxiliary power override.
Available in 10-lead MSOP and 3mm x 3mm DFN packages, the LT4275AHMS#PBF is suitable for demanding applications such as high power wireless data systems, outdoor security camera equipment, commercial and public information displays, and high-temperature industrial environments. It boasts an absolute maximum input voltage of 100V and a wide junction temperature range of -40°C to 125°C.
