A common problem area in switching regulator design is the inductor, and the most common difficulty is saturation. An inductor is saturated when it cannot hold any more magnetic flux. As an inductor arrives at saturation it begins to look more resistive and less inductive. Under these conditions current flow is limited only by the inductor’s DC copper resistance and the source capacity. This is why saturation often results in destructive failures.
While saturation is a prime concern, cost, heating, size, availability and desired performance are also significant. ...
