DALLAS, Nov. 30,
2023 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq:
TXN) today announced the expansion of its low-power gallium nitride
(GaN) portfolio, designed to help improve power density, maximize
system efficiency, and shrink the size of AC/DC consumer power
electronics and industrial systems. TI's overall portfolio of GaN
field-effect transistors (FETs) with integrated gate drivers
addresses common thermal design challenges, keeping adapters cooler
while pushing more power in a smaller footprint.
For more information, see TI.com/LMG3622.
"Today's consumers want smaller, lighter and more portable power
adapters that also provide fast, energy-efficient charging," said
Kannan Soundarapandian, general
manager of High Voltage Power at TI. "With the expansion of our
portfolio, designers can bring the power-density benefits of
low-power GaN technology to more applications that consumers use
every day, such as mobile phone and laptop adapters, TV
power-supply units, and USB wall outlets. Additionally, TI's
portfolio also addresses the growing demand for high efficiency and
compact designs in industrial systems such as power tools and
server auxiliary power supplies."
The new portfolio of GaN FETs with integrated gate drivers,
which includes the LMG3622, LMG3624 and LMG3626, offers the
industry's most accurate integrated current sensing. This
functionality helps designers achieve maximum efficiency by
eliminating the need for an external shunt resistor and reducing
associated power losses by as much as 94% when compared to
traditional current-sensing circuits used with discrete GaN and
silicon FETs.
Maximize energy efficiency and simplify thermal
design
TI's GaN FETs with integrated gate drivers enable
faster switching speeds, which helps keep adapters from
overheating. Designers can reach up to 94% system efficiency for
<75-W AC/DC applications or above 95% system efficiency for
>75-W AC/DC applications. The new devices help designers reduce
the solution size of a typical 67-W power adapter by as much as 50%
compared to silicon-based solutions.
The portfolio is also optimized for the most common topologies
in AC/DC power conversion, such as quasi-resonant flyback,
asymmetrical half bridge flyback, inductor-inductor-converter,
totem-pole power factor correction and active clamp flyback.
To learn more about the benefits of TI GaN for the most common
AC/DC topologies, read the technical article, "The benefits of
low-power GaN in common AC/DC power topologies."
Long-term investment in GaN manufacturing
TI has a
long history of globally owned, regionally diverse internal
manufacturing operations, including wafer fabs, assembly and test
factories, and bump and probe facilities across 15 worldwide sites.
TI has been investing in manufacturing GaN technology for more than
10 years.
With plans to manufacture more than 90% of its products
internally by 2030, TI has the ability to provide customers with
dependable capacity for decades to come.
