The company said that it is now able to provide a comprehensive solution set comprised of turnkey amplifier designs, power supplies, and boost converters that will allow designers across auto, home, and professional markets to mix and match designs to maximise performance for their specific applications.
The new designs are optimised for sound quality, efficiency (no heatsinks), size, and cost—while enabling audio design engineers to create premium audio products more quickly at affordable prices while reducing time to market.
GaN Systems’ power transistors are critical components of next-generation audio products and address essential needs in the Class D audio market, which is expected to reach $3.6bn by 2024, according to analyst figures.
Contributing to that expected growth is rising demand for consumer electronics and smart home devices, growing traction in the in-vehicle infotainment systems in vehicles and a rise in demand for energy-efficient technologies in portable and compact devices.
The two new high-voltage boost converter reference resigns include a 210W continuous/300W peak power source and a 300W continuous/500 W peak power source for manufacturers of stand-alone mono, stereo, and multi-channel automotive and marine amplifiers.
The audio boost converter solutions include wide-range DC supply voltage input from 9VDC to 16VDC operation, 32V output, and are load dump compatible with differential-primary-drive transformer topology.
The OL200DS and CL200M are self-contained 200W-per-channel Class-D amplifier modules designed for manufacturers of powered loudspeakers and stand-alone stereo and multi-channel amplifiers. The GaN Systems OL200DS is designed as two independent half-bridge outputs for both stereo and single-channel applications. The GaN open loop approach provides a switching form for Class D amplifiers with fewer downsides than silicon. The high switching signal performance delivers a dual feedback loop that performs better than a single loop / closed filter.
Details of the OL200DS include:
- 200W/channel, 8 ohms, BTL x 2
- 50W/channel, 8 ohms, x 4 Half-Bridge
- < 0.1% THD+N, 200W, > 114dB SNR
With the GaN Systems CL200M, a heat sink is not required under normal conditions. Thermal protection is provided for worst-case thermal environments, and 96% efficiency reduces heat and system size.
Details of the CL200M include:
- 200W/channel, 8 ohms
- < 0.04% THD+N, 200W, > 108dB SNR
- Dual half-bridge or bridge-tied-load (BTL) topology for ground-referenced output
“With this announcement we are continuing to revolutionise GaN-powered audio, delivering a comprehensive solution set of building blocks for manufacturers to easily launch superior sounding, higher-performance, smaller, and more efficient audio systems for their specific applications,” said Jim Witham, CEO of GaN Systems. “Our expansion into the rapidly growing automotive, marine, and battery-powered vehicles markets brings the advantages of GaN Audio to even more consumers.”
