Data centers, telecommunications equipment, and many industrial applications require larger power supplies, while also demanding reduced system size, weight, environmental impact, and cost. This presents engineers with the challenge of finding new ways to achieve higher power levels in the same or smaller form factor while improving thermal performance.

Texas Instruments (TI) today announced that LITEON Technology has selected TI's highly integrated gallium nitride (GaN) field-effect transistors (FETs) and C2000™ real-time microcontrollers (MCUs) for its latest high-performance server power supplies (PSUs) for the North American market.

The newly commercialized PSU leverages TI's LMG3522R030 GaN FET and TMS320F28003x C2000 real-time MCU to deliver a power density exceeding 95 W/in³ and meets the 80 Plus Titanium standard, the company said.

Lite-On Technology, a global leader in power management solutions, provides power supplies for data centers. To address the power density challenges and requirements of future power supplies, Lite-On Technology implemented a flexible daughter-card design utilizing TI GaN and C2000 real-time MCUs. This design approach also allows engineers to scale the design to meet different power supply requirements, accelerating project design cycles.

LITE-ON Technology design engineers collaborated with TI experts to optimize the power loop and daughter card layout, accelerating the adoption of GaN technology in PSU designs. Leveraging TI's expertise in power FET and controller design, LITE-ON Technology enhanced PSU reliability through comprehensive system-level validation. TI's C2000 real-time MCUs and GaN's flexible, high-resolution pulse-width modulation (PWM) operation help engineers implement high switching frequencies, advanced topologies, and switching schemes.

“Our collaboration with Lite-On Technology demonstrates how TI can address and support engineers’ high-voltage system needs with our end-to-end system know-how and specialized high-voltage semiconductor portfolio,” said Luke Lee, vice president and general manager, Taiwan, Korea and South Asia, TI Asia Pacific. “Combining the powerful performance of TI GaN products with C2000™ real-time MCUs will enable engineers to better meet their needs for smaller, more reliable systems.”

“As a leader in server power supplies, Lite-On Technology responds to emerging challenges with innovative solutions as new technologies emerge,” said John Chang, President of the Cloud Infrastructure Systems and Platforms Business Unit at Lite-On Technology. “High-performance servers require more power in less space, making high power output, conversion efficiency, miniaturized components, and heat management critical.”
