LT4275AHMS#PBF Description

Short technical summary and product information.

The LT4275AHMS#PBF is a versatile Power over Ethernet (PoE) Powered Device (PD) controller manufactured by Analog Devices Inc. This IC is designed to be compatible with IEEE 802.3af, 802.3at (PoE+), and the higher power LTPoE++ standards, capable of delivering up to 90W at the PD RJ45 connector.

 

Key electrical specifications include an operating voltage range of 23V to 60V and a maximum current draw of 2mA. The controller operates across a wide temperature range from -40°C to 125°C, making it suitable for demanding industrial applications. It features an internal charge pump for an N-channel MOSFET solution, optimizing power delivery and system efficiency. The device also includes essential features like a power good output, on-board signature resistor, undervoltage lockout, and thermal protection.

 

Packaged in a 10-MSOP or 10-TFSOP, the LT4275AHMS#PBF is designed for surface mount applications. Its robust feature set and support for multiple PoE standards make it an ideal choice for high-power wireless data systems, outdoor security camera equipment, commercial displays, and other industrial applications requiring reliable power delivery over Ethernet infrastructure.
