摘要：

A new planar microtransformer for use in microswitching 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 about 0.3-mm thick, and 3 x 4 mm2. Its coils provide a relatively high inductance of 33 nH/mm2. This microtransformer is implemented in a forward converter, which operates well at 32 MHz.
