Abstract
A method includes forming one or more capacitors over a substrate. The method also includes forming a transformer at least partially over the substrate. The transformer is adjacent to at least one of the one or more capacitors. At least a portion of the transformer is formed at a same level over the substrate as the one or more capacitors. The method further includes coupling the one or more capacitors and the transformer to at least one embedded integrated circuit die. The one or more capacitors, the transformer, and the at least one embedded integrated circuit die form at least part of a light emitting diode (LED) driver.
