New products, demonstrations and industry presentations will
help power designers reduce EMI and noise, and improve power
density and reliability
DALLAS, March 17, 2022 /PRNewswire/ -- Texas
Instruments (TI) (Nasdaq: TXN) will demonstrate at the Applied
Power Electronics Conference (APEC) how engineers can overcome some
of their most pressing power-management design challenges. From
March 20 through 24 in booth No. 514,
the company will showcase the newest additions to its
power-management portfolio and demonstrate system-level solutions
for increasing power density; reducing electromagnetic interference
(EMI), noise and quiescent current (IQ); and extending
reliability. Power experts will also lead 16 industry and technical
sessions on these topics at the event in Houston. To view virtual demos and related
white papers, technical articles and on-demand training, see
TI.com/APEC.
"For decades, TI has been at the forefront of developing new
processes, packaging and circuit-design technologies that help
power designers achieve higher power density, extend battery life,
reduce EMI, preserve power and signal integrity, and maintain
reliability in their systems," said Mark
Gary, senior vice president, Analog Power Products. "Our
commitment to delivering next-generation power-management solutions
is helping engineers achieve new levels of performance, improve
energy efficiency and increase reliability in applications
ranging from automotive powertrain and body electronics to
electric vehicle (EV) charging, solar power and medical
equipment."
TI is debuting three new products at APEC to help engineers
mitigate EMI and noise in their systems:
- The 36-V, 3-A LMQ66430 and LMQ66430-Q1 buck converters
integrate two input bypass capacitors and one boot capacitor,
enabling engineers to easily meet Comité International Spécial des
Perturbations Radioélectriques (CISPR) 25 Class 5 EMI standards
while offering a best-in-class total solution size,
industry-leading 1.5-µA quiescent current (IQ) and
reduced bill-of-materials costs. To learn more about the benefits
of these devices, read the technical article, "Using buck
regulators with integrated capacitors to lower EMI and save board
space."
- The TPS7A94 low-dropout (LDO) linear regulator combines the
industry's lowest noise of 0.46 µVRMS – at least 42%
better than competing solutions – with a high power-supply
rejection ratio, helping designers improve system accuracy and
precision in highly sensitive applications such as medical
equipment, wireless infrastructure and radar. To learn more, read
the technical article, "LDO basics: noise – part 1."
Innovative solutions push power further
At booth No.
514 and virtually at TI.com/APEC, TI will demonstrate how its
products can help engineers overcome critical power-management
design challenges such as:
- Increasing power density through an 800-V, 11-kW
three-level, three-phase, gallium nitride (GaN)-based active
neutral-point clamped (ANPC) inverter power stage: This demo is
based on a 6.6-kW ANPC inverter reference design and showcases the
600-V LMG3422R030 GaN field effect transistor (FET), which enables
a high switching frequency to reduce magnetics size, increase power
density, and achieve a 98.5% peak efficiency in EV-charging and
solar-power applications.
- Lowering EMI in automotive and industrial applications
while improving filter size: In this demo, the LMQ66430-Q1 low-EMI
buck converter reduces EMI in real time by leveraging a proprietary
dual random spread-spectrum technique, while also showing how
integrated capacitors greatly simplify designs.
- Enabling safer systems with high-voltage isolation
technologies that provide reliable operation: Based on an
Automotive Safety Integrity Level (ASIL) D safety concept-assessed
high-speed traction inverter reference design, this demo leverages
TI's UCC5870-Q1 isolated gate driver and UCC14240-Q1 isolated DC/DC
bias supply module to enable high system efficiency with 30 A of
peak current, while maintaining system reliability through advanced
high-voltage isolation, protection and diagnostics.
- Extending battery life in EV and hybrid EV powertrain
systems: This 7-kW onboard-charger demo features TI's REF35
ultra-low-IQ voltage reference for precision amplifiers,
LMG3522R030-Q1 automotive GaN FET and TMS320F280039C C2000™
real-time microcontroller, to help minimize power consumption and
achieve >96% system efficiency.
- Enhancing the power and signal integrity of low-voltage
devices such as voltage-controlled oscillators, analog-to-digital
converters, digital-to-analog converters and high-end processors:
This demo showcases the impact of different stimuli on a power
supply that uses the TPS7A94, the industry's lowest-noise LDO,
which can achieve 0.46 µVRMS of noise from 10 Hz to 100
kHz.
TI power experts present technologies enabling the
future
Throughout APEC, TI experts will share insights into
the technologies that are making it possible to enhance
system-level performance now and in the future. APEC attendees can
explore topics such as achieving low EMI using a dual random
spread-spectrum scheme; driving power density higher using 650-V
GaN FETs in 800-V power converters; and delivering the most
advanced protection and diagnostics with isolated gate drivers for
automotive applications. The full schedule of industry and
technical sessions hosted by TI experts is available now at
TI.com/APEC.
