Exceptional design flexibility
A growing number of designers with a background in Class AB currently face a big learning curve as they are tasked to design Class D applications. This situation also results in longer time to market cycles. Above all, to be successful these designers need well-tested, production-ready reference designs to help realize their projects. Additional must-haves include optimal PCB layout, housekeeping peripheral interfaces and a selection of key component.
