Power over Ethernet (PoE) controllers, such as the NCP1081DEG, are devices that are used to monitor and control the flow of power over a network. This type of device is typically used to provide power to devices such as text and communication equipment as well as computers, video surveillance systems, VoIP systems and industrial automation networks. The NCP1081DEG is a device that is designed to be used in these types of applications.

The NCP1081DEG is a single-stage high-efficiency PoE controller. It is designed to provide a maximum output of 25 watts per port. The device can support up to eight ports and is capable of delivering up to 1A of continuous current on each port. The device also has a switchable output that can be used to supply a variety of voltages. The device is capable of operating at temperatures of -40 °C to +85 °C and has an efficiency of up to 96%.

The NCP1081DEG has a built-in smart current limiter which helps protect attached equipment from overloaded power, short circuit and thermal overload. It also integrates three types of the IEEE 802.3af/at (Power-over-Ethernet) standards, allowing it to work with any PoE compatible device. The device also includes an SRP (Surge Ring Protection) function to protect against transient over. surge protection.

The NCP1081DEG has an application field of Power-over-Ethernet (PoE) applications. It is designed to provide control and power over the Ethernet. It is compatible with the IEEE 802.3af/at standard and can support two-pair and four-pair power over Ethernet PD (power-distribution) systems. The device is also designed to be used in PoE networks such as VoIP systems and Video surveillance.

The NCP1081DEG has a working principle that is based on a switching regulator-based pulse-width modulation (PWM) architecture. The device is designed to work with a host processor, such as an external microcontroller, to monitor the input and output voltages of the system and control the converter\'s output voltage levels. The device uses a single-stage synchronous buck topology that is capable of providing an output voltage that is adjustable from 3.3V to 25V. The device is also capable of providing a maximum output current of 25 watts per port.

The NCP1081DEG has an input voltage range that ranges from 3.3V to 32V. The maximum input current is 1.2A and the maximum output current is 15A. The device has been designed to be used in a variety of applications with a wide range of operating temperatures and environmental conditions. The device also has an enable controller pin that can be used to enable or disable the device when not in use.

In conclusion, the NCP1081DEG is a device that is well suited for power-over-Ethernet applications. It is capable of delivering up to 25 watts of power per port and has a built-in smart current limiter to protect against short circuit and thermal overload. The device is also compatible with the IEEE 802.3af/at standard and is capable of operating at temperatures of -40 °C to +85 °C. The device also has a switchable output that can be used to supply a variety of voltages. The device also has an input voltage range of 3.3V to 32V and a maximum output current of 15A.
