Outline of Final Research Achievements |
In this study, in order to realize the DC power supply to CMOS logic LSI, power inductors embedded in an organic interposer using two types of magnetic cores (Zn-Fe ferrite thick film and carbonyl-iron/epoxy composite thick film) have been developed, and the CMOS switch buck DC-DC converter has been developed and evaluated. The developed 180 nm-CMOS switch buck DC-DC converter with embedded Zn-Fe ferrite core inductor has typical specifications as follows; switching frequency; 50 MHz, main circuit conversion efficiency; 74% at 2 V input/0.855V-1A output condition. The interposer-embedded power inductor and interposer-integrated CMOS switch DC-DC converter technologies will enable to realize the package-level DC power grid contributing to save electric energy in various electronic systems.
