The LTC4263CDE#TRPBF is an integrated high power, high efficiency power over Ethernet (PoE) controller. The controller is designed for Ethernet networks requiring high power and high efficiency to power devices at the lower end of the IEEE 802.3af standard. The LTC4263CDE#TRPBF includes a high side and low side power switch, a power good comparator, a voltage reference, a current limit and all the necessary circuitry to implement a complete IEEE 802.3af system.

The LTC4263CDE#TRPBF’s power switch operates directly from the voltage supply, allowing for single supply systems with no external components. The switch is powered from 6V to 54V, making it suitable for all types of Ethernet applications. It also provides high efficiency in operation, up to 94%.

The LTC4263CDE#TRPBF contains a power good comparator, which monitors the output voltage in order to ensure that the circuit is powered. The voltage reference ensures the accuracy of the voltage measurement. A free running timer ensures that the power switch does not stay on for too long if the device has been disconnected for more than 5 milliseconds.

A fixed current limit block is incorporated in the power switch to protect the circuit from excessive current drawn by the device. The current limit of 10 Amps allows the LTC4263CDE#TRPBF to efficiently power devices that require greater than 13 Watts of power. Additionally, the LTC4263CDE#TRPBF provides a soft start function to limit power surges that may occur during the start up process.

The LTC4263CDE#TRPBF can be used in a wide variety of applications such as PoE-enabled Ethernet switches, wireless access points and security cameras. The IEEE 802.3af compliant system makes it easy to design and develop a variety of power over Ethernet products. The controller provides excellent flexibility and performance, and is suitable for a variety of PoE applications.

The LTC4263CDE#TRPBF is an ideal controller for powering PoE-enabled devices. It is designed to meet the power requirements of any application, and provides high efficiency, current limit and soft start functions for reliable operation. It is ideal for any applications that require a reliable power over Ethernet controller.
