초록

An integrated inductor using the low temperature cofiring ceramics(LTCC) technology was fabricated. The inductor has Ag circular spiral coil with 16 turns (2-turn x 8-layer) and has a dimension of 11.52mm diameter and 0.71mm thick. For the fabricated inductor, calculation method of inductance was given and it is confirmed that the calculated value is very close to the measured one. Finally as an application of the LTCC integrated inductor to low power electronic circuits, a LTCC buck DC/DC converter with 1.32W output power and 1MHz switching frequency using the inductor fabricated was developed. For the converter the maximum efficiency of about 81% was obtained.
