This application note (PDF) from TI discusses the different aspects of the Overture series high-power solutions, and discusses three application circuits: parallel, bridged, and bridged/parallel configurations
The objective is to provide simple high-power solutions that are conservatively designed, highly reliable and have low part count. This document provides three specific, but not unique, application circuits that provide output power of 100W, 200W,
and above. These circuits are the parallel, bridged, and bridged/parallel configurations.
These three circuits are simple to understand, simple to build and require very few external components compared
to discrete power amplifier designs. Simplicity of design and few components make this solution much more reliable than discrete amplifiers. In addition, these circuits inherently possess the full protection of each individual IC that is very difficult and time consuming to design discretely. Finally, these circuits are well know and have been in industry for years.
