Abstract
A method for planar inductor design has been established on the basis of a discussion of the magnetic flux density distribution. Planar inductors for miniature DC-DC converters have been developed using this design method. This converter is much smaller and thinner than conventional ones, and has an output power/volume ratio of 1.7 W/cc. A spiral coil with a very small distance between the conductors and a low loss magnetic sheet are required for the development of high Q planar inductors
