Why do switching power supplies use Schottky diodes?

Answer: The reason why switching power supplies use Schottky diodes is mainly because using Schottky diodes as rectifier s can increase the switching frequency; On the other hand, it can improve efficiency. But another common use of Schottky diodes is as clamp diodes at the output end, mainly utilizing their short reverse recovery time and quick and timely clamping; Also, by utilizing its small forward conduction voltage drop, it has a small impact on the clamping voltage. Moreover, Schottky diodes have short reverse recovery time and fast speed, and are commonly used for switching power supply rectification.
