Abstract
A 3-D package structure for isolated power module is discussed. The package structure has metal trace in a support layer (e.g. a substrate board), which is covered by two magnetic films from both sides, thus an effective transformer is formed. An IC die which contains a voltage regulator is stacked above the support layer, which significantly reduces the package size.
