GaN Systems adds Class D audio amps
Company extends GaN-powered audio range to enable smaller, and more efficient Class D audio systems vs. silicon
GaN Systems has released two complete Class-D high-performance GaN FET amplifier boards and two complete audio boost converter solutions for marine, auto, and battery-powered vehicles.
Then company says it now provides a comprehensive solution set comprised of turnkey amplifier designs, power supplies, and boost converters—allowing audio systems 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.
The two new high-voltage boost converter reference resigns include a 210-watt continuous/300-watt peak power source and a 300-watt continuous/500-watt peak power source for manufacturers of stand-alone mono, stereo, and multi-channel automotive and marine amplifiers. The complete 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 200-watt-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 is said to provide an ideal 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.
“With today’s 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.”
