Class D Audio Applications
I recently came on board with a company which manufactures portable sound systems, as Manager of New Product Development. Out of respect to the forum, I will try my best not to make this read like a sales pitch for my new company.
We have a unit which is similar in size of an L100, has a powered 2-way speaker system, built-in 3 channel mixer, tape and cd, as well as an available selection of additional accessories we can offer. It is powered by two rechargeable industrial batteries that develop 12 volts DC. The power amp is a true class D 100 watt (peak) design. At this time we are developing more powerful models to be released soon.
The class D design is remarkably energy efficient allowing hours of use from a single battery charge. The circuit also runs very cool; no massive heat sinks needed as in class A, AB or B type circuitry. Furthermore, we're getting good fidelity from our amp design.
