Transphorm GaN Moves Into PC Gaming Market With CORSAIR


Transphorm designer and manufacturing of the highest
reliability and only qualified high voltage Gallium Nitride (GaN)
semiconductors"”have confirmed that its GaN FETs are used in CORSAIR's new
AX1600i Power Supply Unit (PSU). CORSAIR supplies the gaming community with
high-performance products used in custom PCs. The company's latest product
establishes a new class of AC to DC PSUs, as it is the first to use GaN and
achieves 99 percent efficiency. Transphorm's GaN increases the PSU's power
output by 6.5 percent in an 11 percent smaller package at the same temperature.

GaN: The New Edge

The AX1600i uses Transphorm's TPH3205WS 650V FETs in a
bridgeless totem-pole power factor correction (PFC)"”the topology that
complements GaN's performance and efficiency potential. With an increase of 6
percent within this topology, CORSAIR's PSU efficiency now earns a better-than
an 80 PLUS Titanium rating. [Previous CORSAIR power supplies used silicon (Si)
superjunction (SJ) MOSFETs in a 2-phased interleaved PFC, reaching 93 percent

"Our objective was to take an already award-winning PSU and
make it better," explained Jon Gerow, PSU R&D Manager, CORSAIR. "We aimed
to maximize output from any PC running on a 115V mains. To do this was, we had
to adopt innovative methods and materials. Transphorm's GaN ultimately gave us
the boost in performance, efficiency and size we wanted along with the high
quality and reliability we needed to confidently release the AX1600i to our

After researching market-available GaN devices, CORSAIR
chose Transphorm's FETs as they enabled the AX1600i to deliver new benchmarks
compared to the previous AX1500i:

output: 1600W, 6.5 percent increase

reduction: 20 mm shorter, 11 percent smaller

impact: equivalent 50°C continuous output

noise impact: slower fan speed, less noise at full load

CORSAIR noted that Transphorm's packaging also played a role
in its selection process. The TPH3205WS comes in a commonly used TO-247
package, reducing some design complexity.

"CORSAIR's brand is built on products that give our
customers a competitive edge, inside and outside of the gaming PC. And,
Transphorm's GaN presented an invaluable opportunity to advance the PSU"”to make
it smaller, quieter, cooler, and, most importantly, more powerful," added

Collaboration: The Transphorm Edge

Transphorm's commitment to high quality and reliability
extends beyond the technology. Gallium Nitride devices are higher frequency,
sometimes requiring different design techniques than previously used with Si.
The company's GaN experts collaborate regularly with customers to provide
guidance as well as to identify areas of opportunity for future platform
innovation and customer design resources.

Regarding the AX1600i project, Transphorm supported CORSAIR
during both the prototyping and the design validation testing phases. CORSAIR
tapped Transphorm's teams on the ground in both Shenzhen, China, and
California, U.S.
