The LTC4278CDKD#PBF is a programmable Power Over Ethernet (PoE) controller for advanced networking and communications applications. It provides the flexibility needed to extend power to the edge of a network, enabling devices to draw power from remote sources such as LEDs, switches, and PC cards. The LTC4278CDKD#PBF can operate in any of the standard six-pin PoE configurations. These include using only two pins for power, or allowing four pins for both power and data.

The LTC4278CDKD#PBF features two independent programmable power output channels which are capable of delivering up to 15W each. These channels can be individually configured via the programming pins, allowing designers to tailor their power solution to the specific application needs. Each output can be programmed to deliver the required power level, or to provide a combination of power, data, and auxiliary power. The LTC4278CDKD#PBF also features built-in thermal and current over-temperature protection for safety purposes.

The LTC4278CDKD#PBF also offers a wide variety of communication interfaces, including I2C, SPI, JTAG, and USB. This allows for easy connection to a variety of devices, including switches, routers, and routers. In addition, the LTC4278CDKD#PBF can operate in either low-side or high-side control mode. This allows designers to optimize their power solution for the application requirements.

In addition to the communication interfaces, the LTC4278CDKD#PBF also includes several features to ensure safe operation. It includes a 1ms response time timer, two-phase over current protection, and a diode-enabled shunt regulator. The shunt regulator helps reduce power consumption, while the timer provides a failsafe mechanism to prevent any sudden power surges. In addition, the two-phase over current protection ensures that only the required power levels are delivered to the device in order to avoid overloads.

The LTC4278CDKD#PBF is an advanced Power over Ethernet (PoE) controller with features that enable designers to design and deploy complex networked systems. It is well-suited for a variety of industrial, automotive, and consumer applications. With its programmable and protected power outputs, it enables applications such as LED lighting, voice over IP, video surveillance, and more to take advantage of the power delivery capability of Power over Ethernet.
