The PM8803TR device is a Power over Ethernet PoE controller used in various applications. It offers a wide range of features that enable efficient and reliable power management for various Ethernet-based systems. The device is designed to provide up to 48-V input power and up to 48-W output power in a compact, low profile form factor. It supports Class 0, Class 1, and Class 4 PoE Plus standards, allowing for a power range of up to 30-W of output power. The device also features a built-in DC-DC converter, allowing for flexibility in power supply design.

The PM8803TR PoE controller works in two steps. First, a primary side controller uses isolated current sensing to obtain the power signal coming from the Ethernet source. The information is then passed to the device’s secondary side controller, which configures the output power and signal parameters of the PoE system. The controller then performs a closed-loop control to maintain proper voltage regulation and current limitation during system operation. The built-in DC-DC converter further provides flexibility in the system design, allowing for a wide operating input voltage range.

The PM8803TR PoE controller is an ideal solution for applications that require high power and low profile, such as access points, routers, LAN switches, CCTV systems, medical equipment, and industrial automation. Its advanced features and robust protection against short-circuits, overloads, and over-temperature conditions make it an ideal choice for reliable power management. Its integrated EMC filter and over-current protection reduce electromagnetic interference and further improve system reliability.

The PM8803TR PoE controller is a highly configurable solution, making it suitable for applications that require wide voltage, current, and power range. Its wide temperature range operation, up to 105°C, makes it a great choice for industrial applications. The device is also RoHS compliant, making it a safe and reliable choice for industrial and commercial applications.

The PM8803TR PoE controller is a flexible and highly configurable power supply solution that enables efficient and reliable power management for various Ethernet based systems. Its wide range of features and robust protection features make it an ideal solution for reliable PoE power management, for use in a range of industrial, commercial, and residential applications.
