In addition to its wide range of applications, the NCP1090DBG is also highly reliable and efficient. Its built-in overvoltage, overcurrent and reverse polarity protection ensure that it can safely transmit power over long distances without any problems. The part is also capable of operating in a wide range of temperatures, from -40°C to 85°C, making it suitable for even the most extreme environmental conditions.

Working Principle

The NCP1090DBG operates on the principle of Power Over Ethernet (PoE). PoE is a technology that enables the transmission of power over data communication links, such as twisted-pair Ethernet cables. The PoE controller takes the incoming data packet and extracts the power from it. It then converts the power into an appropriate voltage, such as 5V or 12V, and sends it over the network.

The controller is designed for use with a single Ethernet Phy, eliminating the need for multiple transformers or other power conversion components. This allows for a more compact and cost-effective solution. In addition, the NCP1090DBG is capable of providing power up to 25.5 watts (at 48V). This makes it ideal for powering larger devices, such as digital signage and LED lighting.

In addition to its power conversion functionality, the NCP1090DBG also offers a wide range of features. It includes integrated fault sensing and monitoring, automatic configuration and classification of connected devices, and integrated Ethernet and data communications. These features make the device suitable for a variety of applications, from healthcare to industrial.

Conclusion

The NCP1090DBG PoE controller is a highly reliable and efficient PoE controller, suitable for a wide range of applications. It features integrated power regulation, extensive fault sensing and monitoring, and automatic configuration and classification of connected devices. It is also designed to meet the requirements of the Power Supplies Safety Standard (PSS) EN60950, making it suitable for medical and other certified applications. With its wide range of features and applications, the NCP 1090DBG is a powerful and reliable PoE solution.
