Reducing Voltage Loss and Heat with an LT4320 Ideal Diode Bridge Rectifier

Ryan Huff - PoE Applications Engineer May 22nd 2013

This short video demonstrates the higher voltage- and thermal-efficiency of an LT4320 Ideal Diode Bridge Rectifier (also known as an Active Diode Bridge Rectifier) over a conventional Schottky diode bridge for a 9V DC input and 3.5A output load current. The ideal diode bridge is also shown to perform 24V AC, 1.5A rectification more efficiently and at cooler temperatures than the passive diode bridge.
