Power Over Ethernet (PoE) controllers are able to provide power to various electronic devices, such as laptops, printers, and IP cameras, by using a single network cable. The LTC4267IDHC-3#PBF is one such controller that is designed to supply up to 30 watts of power at up to 25.5 volts. This makes it ideal for applications in which higher-power PoE devices need to be powered, such as IP surveillance cameras and LED lighting.The LTC4267IDHC-3#PBF is a single-channel, buck-boost controller with integrated power MOSFETs. It is capable of operating from any DC power source between 14 and 53 volts, and can output up to 30 watts of power at up to 25.5 volts. The controller includes a wide range of protection features, including over-voltage, under-voltage, over-temperature, over-current and short circuit protection.The LTC4267IDHC-3#PBF is designed to provide maximum system efficiency, which is achieved by optimizing the power output for varying load levels and temperature conditions. For example, at light load conditions it operates in low-loss, hysteretic mode, while at high load conditions it operates in pulse-skipping mode. Additionally, the controller has an internal wide-range temperature compensation routine that adjusts the output voltage in response to changes in ambient temperature.The device also includes a multitude of features to enable easy system integration. First, the LTC4267IDHC-3#PBF includes an adjustable output voltage, allowing for optimization of the power delivery for any given application. Additionally, it has a programmable over-voltage protection threshold and a programmable timer for inrush current control. Finally, it has an integrated shutdown capability that allows the output voltage to be shut down in the case of an over-temperature event.Overall, the LTC4267IDHC-3#PBF is an ideal solution for applications requiring a robust and reliable single-channel power over Ethernet solution. Its wide range of features and protection capabilities make it well suited for a variety of demanding applications. Additionally, its optimized power delivery capabilities ensure maximum efficiency and minimum power loss, making it an optimal choice for higher-power PoE applications.
