Due to the increasing market demand for compact, lightweight, highly integrated and energy efficient audio equipment, leading audio equipment manufacturers are striving to meet this demand while continuously improving sound quality. In addition, they must be seamless, cost effective, and provide user-friendly features, which makes the development of audio products more complex. To address these challenges, SounDigital integrated Infineon Technologies' CoolGaN transistors in its new 1500 W Class D amplifier, which supports 800 kHz switching frequencies and five channels, with Infineon's advanced gallium nitride (GaN) technology. Improved energy efficiency by 5% and reduced energy consumption by 60%.

Juliano Anflor, CEO of SounDigital, said: "We are delighted to use Infineon's GaN power semiconductors to enhance the performance of our audio amplifiers, inspiring people and bringing joy by delivering music to the world. GaN transistors not only greatly improve overall system performance, but also reduce system costs and improve ease of use to a greater extent."

Johannes Schoiswohl, Head of the GaN Business Line at Infineon, said: "GaN technology is deeply transforming the audio amplifier industry with its leading efficiency and performance. Infineon's advanced GaN solutions deliver superior sound quality, higher power density and lower energy consumption, taking SounDigital sound systems to the next level of fidelity and performance."

The SounDigital 1500 W Class D amplifier uses Infineon's 100 V normally off E-mode transistors, including the IGC033S101 in PQFN-3x5 and IGB110S101 in PQFN-3x3. Their low on-resistance makes them suitable for demanding high-current applications and significantly improves the sound quality and efficiency of SounDigital amplifiers. Gan-based amplifiers deliver high performance while reducing power dissipation by 75 W and reducing heat sink size by 50%. In addition, the overall system size has been reduced by 40% without compromising performance. CoolGaN transistors further improve audio quality, reducing total harmonic distortion (THD) by 70%, enabling a more accurate and nuanced sound experience, and significantly improving energy efficiency by reducing standby current by 40%.
