The inductor selection process for a 3.3V, 5.0V, or 12V fixed output design is as simple as 1, 2, 3. To determine the values of other components, such as output capacitors, catch diodes, or input capacitors, refer to the Texas Instruments data sheets for LM2594 or LM2597 series switching regulators. Continue by reading these steps and review the inductor selection graphs in the next three slides, as well as the inductor chart, then proceed to the practical exercise.
