This application note presents the types of core materials used in power inductors. It also briefly discusses the core saturation, core loss, as well as the Equivalent Series Resistance (ESR). This ...

Power architectures with nonisolated voltage regulation continue to evolve, and power inductor designs are fundamental to the success of the new product designs. The trend toward two-stage conversion ...

“Drum core” is used to describe the shape of the ferrite core used in some power inductors, and it differentiates these inductors from other types such as toroidal, power bead, flat coil, or planar.

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...
