CoaxMIL 2.0 – Next Generation Coaxial Magnetic Integrated Inductors for Higher Efficiency Fully Integrated Voltage Regulator

Power demand on computing microprocessors has been increasing steadily, demanding more efficient high density power delivery solutions. This work introduces a next-generation package integrated coaxial magnetic integrated inductor (CoaxMIL) developed with a new magnetic material and improved plating technology for significantly higher performance power delivery over prior integrated inductors. The process of optimizing CoaxMIL is presented, followed by simulation and measurement results.
