  • Abstract
    A novel planar microtransformer for use in micro-switching converters of portable equipment is described. This microtransformer, consisting of planar coils and CoZrRe amorphous magnetic layers on a Si substrate, is fabricated by a dry process. It is approximately 0.3 mm thick and 4×4 mm2. The coils have relatively high inductance of 50 nH/mm2. This microtransformer is used in a primary-controlled forward converter, which operates well at 32 MHz
