March 20, 2025 /SemiMedia/ — Texas Instruments (TI) has introduced new power management solutions to address the increasing power demands of modern data centers. As high-performance computing and artificial intelligence (AI) adoption accelerate, data centers require more power-dense and efficient solutions. TI’s new TPS1685 is the industry’s first 48V integrated hot-swap eFuse with power-path protection, designed to enhance the reliability of data center hardware. To simplify power system design, TI also launched a family of integrated GaN power stages—LMG3650R035, LMG3650R025, and LMG3650R070—in industry-standard TOLL packaging.

“With data centers consuming more energy, smarter and more efficient semiconductors are essential to powering the world’s digital infrastructure,” said Robert Taylor, general manager, Industrial Power Design Services. “While advanced chips drive AI’s computational power, analog semiconductors play a critical role in maximizing energy efficiency. Our latest power-management innovations help data centers reduce energy consumption while meeting the demands of an increasingly digital world.”

To improve efficiency and scalability, data centers are shifting to 48V power architectures to support CPUs, GPUs, and AI accelerators. TI’s TPS1685 48V stackable hot-swap eFuse features power-path protection, enabling designers to handle >6kW processing loads with a scalable solution that reduces circuit size by 50% compared to existing hot-swap controllers.

Additionally, TI's new GaN power stage family offers a high-performance solution in TOLL-standard packaging, allowing engineers to integrate TI GaN efficiency without complex redesigns. LMG3650R035, LMG3650R070, and LMG3650R025 incorporate a high-performance gate driver and a 650V GaN FET, achieving >98% efficiency and >100W/in³ power density. These devices also feature advanced protection functions, including overcurrent, short-circuit, and over-temperature protection, which are critical for AC/DC applications such as server power supplies, where high power output must be achieved within limited space.

Preproduction quantities of the TPS1685, LMG3650R035, LMG3650R070 and LMG3650R025 are available now.
