Abstract

Electronic products such as phone handsets and table PC have been highly-miniaturized, and their functionality and performance have increased. In particular, high power density integrated passives accelerate industrial and consumer applications of one-chip DC-to-DC converters, since the converters which are closer to the load were required in order to minimize efficiency losses and reduce the effects of interconnect parasitics[1]. Herein, this paper reports the electric performances of a planar toroidal inductor with Fe-system magnetic flake composites integrated to a test SiP converter. The proposed inductor with the magnetic flake composite offers 1-10 W solution in the frequency range between 1-10 MHz and can be thinner than bulky ferrite inductors while thicker than sputter-deposited thin film inductors because of thick film composite structure of an amorphous Fe-B-Si-C magnetic flakes with high saturation magnetization (1.64 Tesla).
