GaN is being embraced in audio, enabling companies to launch better sounding, higher-performance, smaller, and more eye-catching audio systems. And GaN Systems is making it easier to reap the benefits of GaN with the introduction of the GeN2 Amplifier and SMPS Reference Design.

GaN Systems released the GeN2 amplifier and companion power supply reference design today. This solution is optimized for sound quality, thermal performance, size, and cost. The evaluation kit includes a 2 channel, 200W per channel (8 ohm) Class-D audio amplifier with 96% efficiency and companion 400W continuous, 550W peak power audio-grade SMPS. It enables audio design engineers to create premium audio products more quickly, reducing time to market and at affordable prices.

This GeN2 reference design features a 20% overall size reduction in the power supply. It has a higher level of protection into lower impedance loads to the amplifier and provides better thermal management resulting in 10°C temperature reduction. In addition to these enormous improvements, GeN2 also lowers bill of materials (BoM) cost.

As entertainment, music, and information have become a more significant part of all aspects of our lives, and with audio consumption at an all-time high, high-quality audio is now a “must-have” across all audio segments. Class-D audio systems with GaN technology provide better sound quality and are smaller and lighter.

The GeN2 reference design allows design engineers to develop a heatsink-less, self-powered (from AC line Input) design with no external DC supplies required and smaller size boards due to a high level of the controller and DSP integration.

The reference design offers high efficiency across a wide load range using GaN transistors and advanced control techniques. Designers can quickly scale to a higher power with magnetics and GaN transistor selection.

Additionally, the solution highlights an easy plug-and-play design with features such as multi-audio signal inputs, bridge-tied load output, and open-loop/closed-loop toggling.

The Streamer Ultra system delivers commanding sound quality and performance in a discreet package, performing the same functions that once required a rack full of components. GaN Systems is helping the company achieve: 5X-10X better THD+N; 20dB better Noise Floor (system level); 4X-5X better Frequency Response 4X reduction in power loss;

GaN Systems’ power transistors are key components of next-generation audio products. While 2021 marked a year where GaN was embraced in the industry, 2022 is anticipated to be even better. GaN Systems predicts an exponential growth of GaN in the Class-D audio market, and 2022 will mark a year when the biggest audio names will launch GaN audio products.
