Finally, the turnaround time for traditional transformers will be shorter than for planar devices. Samples can be wound in a matter of days and adjustments can be quickly made to optimize the performance. Planar devices require a printed-circuit layout and tooling for the magnetic core materials. In very-high-volume, higher-power applications, planar devices will provide the higher performance and economical solution. But traditional magnetics will be the answer for nearly every other application.
Working with a qualified supplier
Ultimately, the best idea is to work with a qualified supplier who understands the benefits and tradeoffs of both transformer types. That way, designers can be assured of a truly optimum solution.
