Design considerations for high frequency buck converter

The paper reports on design, simulation and development of a test bed prototype for microfabricated, chip-integrated inductor developed by Tyndall National Institute, Cork, Ireland. A test circuit is developed for a buck DC/DC converter topology. The device is powered from Li-Ion battery or with use of a similar source (approximately 3.6 V) and should be able to deliver approximate 0.5 W with output voltage of 1.0-1.2 V. The main issue is to achieve high switching frequency-between 5 MHz and 15 MHz.
