The LT4276BHUFD#TRPBF is a Power over Ethernet (PoE) Powered Device (PD) controller from Analog Devices, designed for both forward and flyback topologies. It supports IEEE 802.3at (PoE+) and IEEE 802.3af (PoE) standards, delivering up to 25.5W of power. The device operates over a wide junction temperature range of -40°C to 125°C and can handle a maximum voltage of 60V.
This controller features auxiliary power support as low as 9V and offers superior surge protection up to 100V. It utilizes an external N-channel MOSFET for the Hot Swap function, enhancing power delivery efficiency and reducing heat dissipation. The LT4276BHUFD#TRPBF is available in a compact 28-lead 4mm x 5mm QFN package with an exposed pad, suitable for surface mounting.
Applications for this controller include high power wireless data systems, outdoor security camera equipment, and commercial/public information displays. Its design facilitates configurable power supply topologies and can operate without an opto-isolator in flyback configurations, simplifying system design.
