Abstract :
A novel low profile power inductor suitable for planar integration is designed and fabricated based on low temperature co-fired ceramics (LTCC) technology for microprocessor power delivery applications. The inductor was designed to operate at a switching frequency of 4 to 5 MHz, carrying a nominal DC current of 20 A with a ripple current of 8 to 10 A in a 5 V to 1 V DC-DC converter. The design and fabrication procedure is discussed in this paper, followed by small signal measurement and magnetic characterization results. The inductor is being implemented in a prototype converter and the measurement results are presented and its performance evaluated
