News highlights:
- The industry's first 48V integrated hot-swap eFuse with
power-path protection streamlines data center design and enables
designers to reach power levels beyond 6kW.
- New integrated gallium nitride (GaN) power stages combine
TI GaN and a high-performance gate driver with advanced protection
features in an industry-standard transistor outline leadless (TOLL)
package.
DALLAS, March 17,
2025 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq:
TXN) today debuted new power-management chips to support the
rapidly growing power needs of modern data centers. As the adoption
of high-performance computing and artificial intelligence (AI)
increases, 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 to support data center
hardware and processing needs. To simplify data center design, TI
also introduced a new family of integrated GaN power stages, the
LMG3650R035, LMG3650R025and LMG3650R070, in industry-standard TOLL
packaging. TI is showcasing these devices at the 2025 Applied Power
Electronics Conference (APEC), March
16-20, in Atlanta,
Georgia.

"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."
Reach power levels beyond 6kW with intelligent system
protection
As power demands surge, data center
designers are shifting to 48V power architectures for enhanced
efficiency and scalability to support components such as CPUs,
graphics processing units and AI hardware accelerators. TI's 48V
stackable integrated hot-swap eFuse with power-path protection
empowers designers to tackle high-power (>6kW) processing needs
with a scalable device that simplifies design and reduces solution
size by half compared to existing hot-swap controllers in the
market.

technical article, "Powering Modern AI Data Centers with an
Integrated 48V Hot-Swap eFuse Device."
Achieve higher efficiency with TI GaN in industry-standard
packaging
In addition, TI introduced a new family of
integrated GaN power stages. The LMG3650R035,
LMG3650R070 and LMG3650R025 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.
The new power stages integrate a high-performance gate driver
with a 650V GaN field-effect transistor (FET) while achieving high
efficiency (>98%) and high-power density
(>100W/in3). They also integrate advanced protection
features including over-current protection, short-circuit
protection and over-temperature protection. This is especially
important for AC/DC applications like server power, where designers
are challenged to push more power into smaller spaces.

packaging, read the technical article, "Developing
industry-standard power supplies with integrated TOLL-packaged GaN
devices."
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.
Throughout the show, TI power experts will lead 27 industry and
technical sessions to address power-management design challenges.
Visit TI in the Georgia World Congress Center, Booth No. 1213. The
full schedule is available at ti.com/APEC.
