Analog Devices Inc. LTC4279IUFD#TRPBF Single-Port Power over Ethernet (PoE) Controller

The LTC4279IUFD#TRPBF is a high-performance, single-port Power over Ethernet (PoE) controller designed by Analog Devices Inc. to deliver power and data over a single Ethernet cable to remote devices. This advanced component is tailored for use in a variety of applications, such as IP cameras, wireless access points, and VoIP phones, where it simplifies the design and deployment of networked devices by eliminating the need for separate power supplies.

The LTC4279IUFD#TRPBF complies with the IEEE 802.3af (PoE), IEEE 802.3at (PoE+), and IEEE 802.3bt (4-pair PoE) standards, ensuring broad compatibility with a wide range of powered devices (PDs). It operates over a wide input voltage range and is capable of delivering up to 90W of power, making it suitable for applications requiring higher power levels.

This PoE controller features an integrated switching regulator that allows for efficient power conversion and minimizes the need for external components. It also includes robust protection features such as overcurrent protection, overvoltage protection, and thermal shutdown to safeguard both the power sourcing equipment (PSE) and the connected PDs against electrical faults and overheating.

The LTC4279IUFD#TRPBF is available in a compact, 24-pin QFN package, which is ideal for space-constrained applications. Moreover, it supports an extended industrial temperature range, making it suitable for use in harsh environments. The controller also includes a programmable classification current to ensure precise control of power allocation for different PDs.

For ease of integration, the LTC4279IUFD#TRPBF is offered in tape and reel packaging (denoted by the suffix 'TRPBF'), facilitating automated manufacturing processes. With its advanced features and compliance with the latest PoE standards, the LTC4279IUFD#TRPBF from Analog Devices Inc. is an excellent choice for designers looking to incorporate reliable power delivery into their networked systems.
