The LT4276BHUFD#TRPBF is a power management integrated circuit (PMIC) used for Power Over Ethernet (PoE) applications. It is designed to provide power over standard Ethernet cables and can work with up to 10 watt PoE applications. The LT4276BHUFD#TRPBF is a bi-directional power converter that provides a low cost, small form factor solution enabling Power Over Ethernet (PoE) applications. The part provides high efficiency step-down DC/DC controller, reverse power protection switch, voltage regulator, and isolated communications isolated power receiver (MOPR).

The working principle of the LT4276BHUFD#TRPBF is based upon voltage or current protection. When the input voltage or current level exceeds the overvoltage or overcurrent threshold, the part will shut down. If a valid PoE signal is detected, the part then switches the output voltage to the required level allowing the connected device to receive power. The output voltage is adjustable from 1.2V to 12V, allowing for a wide range of possible applications.
