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.

Simple and clear. But nothing about core losses?

We're glad you found it helpful. We do touch on core losses in our "Determining Inductor Power Losses" application note. You can find it here: http://www.coilcraft.com/pdfs/doc486_inductorlosses.pdf You also might want to check out our Inductor Core and Winding Loss Calculator: http://www.coilcraft.com/apps/loss/loss_1.cfm Thank you!
