The authors describe the development of a planar inductor and its application to DC-DC converters. The planar inductor fabricated had a small size (11 × 11 × 0.8 mm), 33 μH inductance, and a maximum quality factor of 14. The very small DC-DC converter, using the planar inductor as an energy storage element, had a 250-kHz switching frequency, a 5-V-2-W typical output, and a power/volume ratio of up to 1.7 W/cm3.
