The power chips help data centers use energy better, support AI and servers, and save space with safe and easy-to-use designs.
Texas Instruments (TI) has introduced new power-management chips to meet the increasing power demands of modern data centers. With the rise of high-performance computing and AI, data centers need more efficient and power-dense solutions. TI’s TPS1685 is the first 48V integrated hot-swap eFuse with power-path protection, designed to support data center hardware and processing. To simplify design, TI has also launched a new family of integrated GaN power stages—LMG3650R035, LMG3650R025, and LMG3650R070—available in industry-standard TOLL packaging.
These products are designed for data center engineers, power system architects, and AI and high-performance computing hardware developers. They are also suitable for server and cloud infrastructure providers and power supply manufacturers designing AC/DC and DC/DC conversion systems.
As power demands grow, data centers are adopting 48V architectures for better efficiency and scalability to support CPUs, GPUs, and AI accelerators. TI’s 48V stackable integrated hot-swap eFuse with power-path protection enables designers to handle high-power needs exceeding 6kW. This scalable solution simplifies design and reduces size by 50% compared to existing hot-swap controllers.
These power stages combine a high-performance gate driver with a 650V GaN FET, achieving over 98% efficiency and more than 100W/in³ power density. They also include advanced protection features such as over-current, short-circuit, and over-temperature protection, making them ideal for AC/DC applications like server power, where maximizing power in limited space is critical.
“With data centers increasingly demanding more energy, powering the world’s digital infrastructure begins with smarter, more efficient semiconductors,” said Robert Taylor, general manager, Industrial Power Design Services. “While advanced chips drive AI’s computational power, analog semiconductors are key to maximizing energy efficiency. Our latest power-management innovations are enabling data centers to reduce their environmental footprint while supporting the growing needs of our digital world.”
