A high-speed silicon FET for efficient DC-DC power conversion
2012 24th International Symposium on Power Semiconductor Devices and ICs, 2012A novel silicon device architecture for DC-DC power conversion is reported. Efficient switching at high frequencies (1–5 MHz) is achieved by simultaneously reducing gate charge, reverse capacitance, and gate resistance while still maintaining good on-state resistance and off-state breakdown voltage.

Electrodeposited Nanolaminated CoNiFe Cores for Ultracompact DC–DC Power Conversion
IEEE Transactions on Power Electronics, 2015Laminated metallic alloy cores (i.e., alternating layers of thin film metallic alloy and insulating material) of appropriate lamination thickness enable suppression of eddy current losses at high frequencies. Magnetic cores comprised of many such laminations yield substantial overall magnetic volume, thereby enabling high-power operation.

Gate Driver Voltage Optimization for Multi-Mode Low Power DC–DC Conversion
Journal of Low Power Electronics, 2009In this paper we propose an optimization method for low power, high-efficiency DC-DC conversion. A detailed analysis of a multi-mode Step-Down (or Buck) converter losses is presented, allowing the comparison of the power MOS channel conduction losses with their gate-driving losses in order to find the optimum gate-driving voltage that maximizes the ...
