Introduction Power supply engineers rarely "design" an inductor for DC-DC converter applications. The preferred approach seems to be to just use an easily available off-the shelf inductor from the nearest components cabinet! The first cut is to choose the inductance, hopefully based on a target value of current ripple ratio r. Then the engineer calculates the worst-case inductor current, hopefully cognizant of what part of the line variation leads to the maximum inductor current. Then he or she tries to find an inductor wi…
