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.

Axign B.V. received an equity investment from KBC Focus Fund as the lead investor, together with Innovation Industries and Oost NL. This investment round enables Axign to mass produce and launch the company’s unique range of audio devices worldwide. Additionally, the new funding will support the development and introduction of next-generation devices for active speakers and streaming audio systems.
