8.2.2.1 Selecting the Rectifier Diode

A Schottky diode is the preferred type for the rectifier diode due to its low forward voltage drop and small reverse recovery charge. Low reverse leakage current is important parameter when selecting the Schottky diode. The diode must be rated to handle the maximum output voltage plus the switching node ringing. Also, it must be able to handle the average output current.
