Selecting the Best Inductor for Your DC-DC Converter
More InfoLess Info
The use of DC-DC converters is increasing. As electronic systems become more miniaturized, mobile, complicated, and popular, the power requirements become more varied. Proper inductor selection requires a good understanding of inductor performance and of how desired in-circuit performance relates to the information available in supplier data sheets. This paper discusses the key performance ratings engineers need to understand and evaluate when specifying power inductors for dc-dc conversion circuits.
