TI New Power-Management Chips For High-Performance Computing

To meet the ever-increasing power requirements of modern data centers, Texas Instruments (TI) introduced new power-management chips. Data centers need more power-dense and effective solutions as high-performance computing and artificial intelligence (AI) become more widely used.TPS1685 48V hot-swap eFuse, GaN Power Stages Data Centers

The first 48V integrated hot-swap eFuse with power-path protection in the industry, the TPS1685 from TI supports the computational and hardware requirements of data centers.

TI also unveiled a new series of integrated GaN power stages, the LMG3650R035, LMG3650R025 and LMG3650R070, in industry-standard TOLL packaging to streamline data center architecture.

These devices will be on display at the 2025 Applied Power Electronics Conference (APEC), which will take place in Atlanta, Georgia, from March 16–20.

Reach power levels beyond 6kW with intelligent system protection 

Data center designers are switching to 48V power architectures as power demands rise in order to accommodate components like CPUs, GPUs, and AI hardware accelerators with greater efficiency and scalability.

In comparison to other hot-swap controllers on the market, TI’s 48V stackable integrated hot-swap eFuse with power-path protection enables designers to address high-power (>6kW) processing requirements with a scalable device that streamlines design and cuts solution size in half. 

Achieve higher efficiency with TI GaN in industry-standard packaging

In addition, TI introduced a new family of integrated GaN power stages. The LMG3650R035, LMG3650R025 and LMG3650R070 leverage the benefits of TI GaN in an industry-standard TOLL package, allowing designers to take advantage of TI GaN efficiency without costly and time-consuming redesigns.

Reimagining Power Density and Efficiency at APEC 2025

At APEC 2025, TI will showcase power solutions that enable designers to reimagine new levels of power density and efficiency, including:

  • Dell’s 1.8kW server power-supply unit (PSU) with TI GaN power stages: Dell’s first high-efficiency 12V PSU design uses a TI integrated GaN power stage. The PSU features a GaN FET with built-in driver, protection and temperature reporting to achieve over 96% system-level efficiency.
  • Vertiv’s 5.5kW server PSU: Part of Vertiv’s PowerDirect Rack DC power system, the latest PSU from Vertiv is powered by TI GaN technology to deliver up to 132kW per rack.
  • Greatwall’s 8kW PSU: To help designers increase power density, Greatwall and TI co-developed an 8kW open-rack PSU using TI GaN technology and TI C2000™ real-time microcontrollers.

In addition to achieving high efficiency (>98%) and high power density (>100W/in3), the new power stages combine a high-performance gate driver with a 650V GaN field-effect transistor (FET) and incorporate advanced protection features like over-current, short-circuit, and over-temperature protection.

These features are particularly crucial for AC/DC applications like server power, where designers must squeeze more power into smaller spaces.

“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.”
