GaN Systems launches 300W Audio Boost Converter SMPS
At the 37th annual IEEE Applied Power Electronics Conference and Exposition (APEC 2022) in Houston, TX, USA (20-24 March), GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) has launched its 300W Audio Boost Converter SMPS (switch-mode power supply). Targeted at automotive, marine, motorcycle and a broad range of 12VDC input applications, the 300W reference design features a complete turnkey platform solution that accelerates time-to-market, delivering improved audio quality and smaller, more streamlined audio systems. GaN Systems’ audio solutions and customer products from Syng, Orchard Audio, Axign and more are on display at GaN Systems booth #1324.
The new 300W continuous, 500W peak power audio-grade SMPS reference design offers a complete solution with a wide-range DC supply voltage input of 9-16VDC, load dump rated, and operates seamlessly with GaN Systems +/-32VDC Dual-Rail output amplifier. Along with wide-range DC supply voltage input, onboard common-mode AC line filter and differential primary drive transformer topology, the platform also provides SCP, OCP, thermal, voltage protection, and auto recovery.
The firm states that GaN delivers improved audio quality, smaller audio systems, more power, and streamlined designs with the elimination of heat-sinks.
At APEC, visitors can see GaN-based audio solutions including the Syng Alpha Cell speaker (named one of TIME’s 100 Best Inventions of 2021), Orchard Audio’s Starkrimson Stereo Ultra amplifier and all-in-one Starkrimson Streamer Ultra, and Axign’s new 500W heatsink-less audio amplifier. Also on display is GaN Systems’ GeN2 Class-D audio amplifier and companion power supply reference design, highlighting a 96% efficiency amplifier and featuring a 20% overall size reduction in the power supply.
