TPS23861PWR

Power Over Ethernet (PoE) Controllers

The TPS23861PWR is a Power over Ethernet (PoE) controller for powering Ethernet-enabled devices using standard twisted pair cabling. This device takes a voltage from an external source, such as an Ethernet network, and outputs a regulated voltage at the same time.

Application field

The TPS23861PWR is ideal for powering devices such as IP phones, printers, security cameras and access points. It is also well suited for any application that requires the reliable delivery of an isolated power supply. The TPS23861PWR is on the Power over Ethernet (PoE) standard, which allows for easy and flexible installation of powered devices.

The TPS23861PWR also supports the 802.3af Power over Ethernet (PoE) standard which can supply up to 15.4 W of regulated power to the Ethernet device. The device is also compliant with IEEE 802.3at, allowing it to supply up to 25.5 W of power to the device. This device is fully compliant with the UL 60950-1 safety regulations, which means it can be safely used in commercial or residential applications.

Working principle

The TPS23861PWR has two major ports: an input port and an output port. The input port is used to receive a voltage from the external source, such as an Ethernet network. This voltage is then rectified to a DC voltage which is then regulated to a constant voltage level. The output port is then used to output the regulated voltage.

The TPS23861PWR also has two other main components: a power management unit and a switching regulator. The power management unit is responsible for ensuring that the output voltage is constant. It monitors the input voltage and can adjust the output voltage to ensure stable, constant power delivery even under varying load conditions. The switching regulator is responsible for delivering the regulated voltage to the output port. It uses Pulse Width Modulation (PWM) to control the output voltage.

The TPS23861PWR also includes protection features to prevent damage to the device, such as over-voltage, under-voltage, over-current and short-circuit protection. On top of this, the device complies with the international safety regulations, further enhancing its reliability and safety.

In conclusion, the TPS23861PWR is an ideal solution for powering Ethernet-enabled devices such as IP phones, printers, security cameras and access points. It is compliant with the Power over Ethernet (PoE) standard and supports up to 25.5 W of output power. Additionally, it has protection features to prevent damage. With its reliable performance, easy installation, and safety, the TPS23861PWR is the perfect choice for a Power over Ethernet (PoE) controller.
