New GaNFast Power ICs Overtake Old, Slow Silicon Chips in Density Power’s 400V, 300W “1/4-Brick” DC-DC Converter.
DUBLIN, IRELAND and SHENZHEN, PRC — (PRWeb) – Navitas Semiconductor Limited and Density Power Solutions (登钛电子) today jointly announced the industry’s first 400V, 300W standard 1/4 brick DC-DC converter using GaNFast power ICs for high-reliability applications such as industrial control systems, communication equipment plus server and telecom distributed power systems.
Gallium Nitride (GaN) is a next-generation power semiconductor technology that runs up to 100x faster than old, slow silicon chips, with dramatic improvements in energy savings and power density. Navitas’ GaNFast power ICs integrate GaN power (FET) with drive, control and protection to enable up to 3x more power in half the size and weight. GaNFast power ICs have been used in the mobile and consumer fast charger market since 2018, with tier-1 adopters including Lenovo, Xiaomi, OPPO and NVIDIA. Now, GaN’s high performance and high reliability can be exploited in 400V high-voltage DC (HVDC) distribution for industrial, telecom and data center applications. Tier-1 IT companies like IBM, China Mobile and HPE use HVDC power distribution to reduce energy loss and heat compared to older AC voltage systems.
The DQB300D375S28 DC-DC converter provides a tightly-regulated 28V nominal output and follows the industry-standard ‘DOSA’ ¼-brick package (60 x 39.1 x 12.7 mm) and pin-out for simple installation and upgrade. Over a wide-range 330-425V DC input, and from -40 ℃ to +100℃ operating temperature, the HQBS delivers the full 300W in only 30 cc without derating. The means a world’s best-in-class power density of 10 W/cc, and 2x-5x more power than any other DOSA high-voltage ¼-brick converter.
Navitas NV6117 GaNFast power ICs are used in an industry-proven, hard-switched half-bridge topology at a record 400 kHz operating frequency, with efficiency as high as 95% at full load, the GaN HQBS saves over half the energy lost as heat by old, silicon converters.. Isolation voltage is industry-standard 2250 VDC and high-quality design and performance deliver a mean-time-between-failures (MTBF) of over 500,000 hours.
Mr. Steven (Kezhi) WANG, General Manager of Density Power Solutions, said: “As the third-generation semiconductor material, gallium nitride brings revolutionary new breakthroughs and design convenience to modular power supplies, and breaks down the restrictions of using traditional, slow, silicon chips. This new design freedom has boosted industrial module power supply performance to a larger market. Navitas’ GaNFast technology, based on gallium nitride, has enabled a historic step forward in the application of modular industrial power supplies. I believe that in the near future, there will be more GaN applications and greater value in the industrial field!”
Mr. Charles (Yingjie) ZHA, Vice President and General Manager of Navitas China, said: “It is great to see the mass production release of this 300W module power supply, which indicates that Navitas’ products have passed the extremely rigorous quality and reliability tests for the harsh industrial market. From our leadership in mobile and consumer fast charging, Navitas has officially entered the high-reliability industrial and communication fields. We look forward to working with more customers to develop more efficient, more energy-saving, and more reliable power products.”
