New Fractal Class-D Audio Amplifier Technology Maximizes Battery Life in TWS Earbuds

Typical Class-D amplifiers are generally tuned to give the highest efficiency when outputting large power levels but have a rather low efficiency at lower power levels. Using a new type of bridge configuration, the patented Fractal Class-D audio amplifier improves the efficiency at lower power levels while maximizing efficiency over a wide range of power levels. Available from SiliconIntervention, this technology was developed by Martin Mallinson, the company's founder and chief scientific officer.
