Abstract :
Summary form only given. The trend for size reduction in portable electronics is driving the integration of passive components onto silicon substrates. Several teams have demonstrated the feasibility of using thin film magnetics for low power conversion. However, the power density achieved are typically of the order of 1 W/cm/sup 2/. Design and fabrication techniques for achieving high power density and high efficiency components have been presented by Brunet et al (16/sup th/ APEC Conf., p.1189-97 (2001)). This paper presents the electrical performance of fabricated E-core micro-transformers and the use of these thin film components in a DC-DC converter.
