SiliconIntervention Announces Availability of Silicon-Based Fractal-D Audio Amplifier Evaluation Board

SiliconIntervention announced the availability of an evaluation board, demonstrating the high efficiency operation of its Fractal-D audio amplifier aimed at wearable applications such as earbuds and smart glasses as well as mobile products that demand extended battery life. SiliconIntervention is the company exploring a new type of bridge configuration that improves the efficiency at lower power levels while maximizing efficiency over a wide range of power levels.

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.

Driven by the need to maximize battery life in portable devices, Class-D efficiency at low output levels is receiving greater attention. This is particularly important to achieve longer battery life in designs such as true wireless earbuds. Power optimized amplification is precisely the goal for Multilevel Class-D, and now there's also Fractal Class-D, a new technology developed by SiliconIntervention, a Canadian company formed in 2019 as the result of the pioneering research and development of its founder Martin Mallinson, the former Chief Scientist at ESS Technology.
