Inductor Apparatus Optimized for Low Power Loss in Class-D Audio Amplifier Applications and Method for Making the Same

Crestron Electronics, Inc.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 7 of these applications claim priority to application 16/436,390, filed Jun 10, 2019. A shared origin can cover several different claimed inventions, which is why members here may not share a title. In-force patents first, soonest term end first, then patent number. Expired patents follow, in the same order.
