摘要： Ceramic inductors are made from stacked sheets of co-fired ceramic. At least one of the ceramic sheets has a slot with a conductor disposed in the slot. The conductor has a thickness equal to a thickness of the ceramic sheet containing the slot. The conductor has a large thickness (compared to prior art co-fired ceramic inductors) and therefore can carry large currents. The present ceramic inductor can be used in power electronics applications due to the ability to carry large currents. The present ceramic inductor preferably has an inductance that decreases with increasing current. A decreasing inductance characteristic tends to increase energy efficiency in a voltage regulator when the inductor is used as an output inductor. Specifically, the variable inductance tends to substantially increase energy efficiency at low current loads without adversely affecting efficiency at high loads.

摘要： A modified planar Low Temperature Co-Fired Ceramic (LTCC) high conductance inductor, embedding a large cross section conductor, supports a stacked arrangement of heat spreader, inductor and active device layers. Interlayer electrical connections connect the layers. Optionally, a DC-DC converter includes the modified planar LTCC high conductance inductor, embedding a large cross section conductor, supporting a stacked arrangement of heat spreader, capacitor and active device layers, the active devices layer including the switching transistors. The active devices layer may include semiconductor dies embedded in a substrate.
