GaN Systems extends Class D portfolio - Electronics Weekly

GaN Systems present provides a merchandise offering comprised of turnkey amplifier designs, powerfulness supplies, and boost converters—allowing audio systems designers crossed auto, home, and nonrecreational markets to premix and lucifer designs to maximize show for their circumstantial applications.

The caller designs are optimized for dependable quality, ratio (no heatsinks), size, and cost—while enabling audio plan engineers to make premium audio products much rapidly astatine affordable prices portion reducing clip to market.

GaN Systems’ powerfulness transistors code needs successful the increasing Class D audio marketplace – driven by rising request for user electronics and astute location devices, much fantabulous traction successful in-vehicle infotainment systems successful automobiles and a emergence successful request for energy-efficient technologies successful portable and compact devices.

210W and 300W Audio Boost Converters: The 2 caller high-voltage boost converter notation resigns see a 210-watt continuous/300-watt highest powerfulness root and a 300-watt continuous/500-watt highest powerfulness root for manufacturers of stand-alone mono, stereo, and multi-channel automotive and marine amplifiers.

The implicit audio boost converter solutions see wide-range DC proviso 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 arsenic 2 autarkic half-bridge outputs for some stereo and single-channel applications.

The GaN unfastened loop attack provides an perfect switching signifier for Class D amplifiers with less downsides than silicon.

The precocious switching awesome show delivers a dual feedback loop that performs amended than a azygous loop / closed filter. Details of the OL200DS include:

• 200 watts/channel, 8 ohms, BTL x 2
• 50 watts/channel, 8 ohms, x 4 Half-Bridge
• < 0.1% THD+N, 200W, > 114dB SNR
• Quad half-bridge oregon dual bridge-tied-load (BTL) Topology for Ground-Referenced Output

With the caller GaN Systems CL200M, a vigor descend is not required nether mean conditions. Thermal extortion is provided for worst-case thermal environments, and 96% ratio reduces vigor and strategy size. Details of the CL200M include:

• 200 watts/channel, 8 ohms
• < 0.04% THD+N, 200W, > 108dB SNR
• Dual half-bridge oregon bridge-tied-load (BTL) topology for ground-referenced output

These caller designs leverage GaN Systems GS61008P GaN powerfulness transistors.
