40V-30A Adjustable Switching Power Supply

A DC-to-DC converter is one of the most commonly used circuit topologies in electronics, especially in power supply applications. There are three main types of DC-to-DC converters (non-isolated): Buck, Boost, and Buck-Boost. Sometimes a buck converter is also called a step-down converter and a boost converter is also called a step-up converter. A buck converter reduces/steps down the input voltage while increasing the output current.

In this article/video, I introduced an adjustable buck converter circuit that can deliver up to 30A and handle up to 40V at the input. The output voltage is adjustable from 3V to 37.5V. Several PCB design rules were followed to enhance output stabilization and current handling, also to reduce the radiated emission, and noise figure.
