DALLAS, Sept. 27, 2021 /PRNewswire/ -- Texas Instruments
(TI) (Nasdaq: TXN) today introduced the industry's smallest and
most accurate 1.5-W isolated DC/DC bias-supply module. The
UCC14240-Q1 uses a proprietary integrated transformer technology to
enable designers to cut their power solution size in half for use
in high-voltage environments such as electric vehicles (EVs),
hybrid EVs, motor-drive systems and grid-tied inverters. For more
information, see ti.com/UCC14240-Q1-pr.
With the accelerating growth of the EV market, automotive design
engineers are looking for ways to improve efficiency and
reliability, while also reducing the weight of the heaviest part of
the EV: the powertrain. To help meet the need for smaller, more
reliable systems to extend driving range, engineers are moving to a
distributed power architecture, a scheme where every isolated gate
driver has a dedicated bias supply. This architecture improves how
the system reacts to single-point failures. For example, if one
bias supply fails, the other bias supplies remain operational, as
do their paired gate drivers— helping to keep a vehicle safely on
the road.
Fully integrated power solutions such as the UCC14240-Q1 help
engineers take advantage of distributed architecture. Learn more by
reading the technical article, "Driving next-generation EV systems
with a distributed architecture in a bias-supply."

Exchange virtual event, Sept. 27-29,
2021. Learn more at ti.com/techexchange.
Extend driving range with industry-leading power density and
system efficiency
The UCC14240-Q1 offers size and efficiency advantages that
enable greater power density and system efficiency, which can allow
vehicles to drive farther between charges. The 3.55-mm height and
small footprint of the UCC14240-Q1 enable designers to reduce the
power solution volume by as much as 50%, packing more power in half
the size. The height reduction also gives engineers the full
flexibility to place the module on either side of the printed
circuit board.
This dual-output power module offers 60% efficiency – twice that
of traditional bias supplies – doubling the power density and
helping increase vehicle driving range. By delivering more than 1.5
W at ambient temperatures of 105°C, the UCC14240-Q1 enables
engineers to drive isolated gate bipolar transistors (IGBTs),
silicon carbide (SiC) and gallium nitride (GaN) switches at high
frequencies.
Achieve high CMTI and ultra-low EMI to speed time to
market
By leveraging TI's integrated transformer technology with a
3.5-pF primary-to-secondary capacitance, the UCC14240-Q1 can
mitigate EMI caused by high-speed switching and comfortably achieve
common-mode transient immunity (CMTI) performance of more than 150
V/ns.
Featuring soft switching, spread-spectrum modulation, shielding
and low parasitics, the UCC14240-Q1 enables designs to more easily
meet the electromagnetic compatibility standards of Comité
International Spécial des Perturbations Radioélectriques (CISPR) 25
and CISPR 32, speeding time to market.
Protect vehicle performance with industry-best accuracy over
temperature and isolation
The UCC14240-Q1's integrated closed-loop control enables ±1.0%
accuracy from -40°C to 150°C. The device's tight tolerance enables
the use of smaller power switches while also improving overcurrent
protection. Fault monitoring, overcurrent protection, overpower
protection and overtemperature protection are all fully integrated.
The UCC14240-Q1 offers third-party-certified 3-kVrms isolation and
delivers the industry's best vibration immunity due to its
ultra-low weight and 3.55-mm height.
Package, availability and pricing
The UCC14240-Q1 is available in pre-production quantities from
TI in a 36-pin, 12.8-mm-by-10.3-mm-by-3.55-mm shrink small-outline
package. Pricing starts at US$4.20 in
1,000-unit quantities. Engineers can evaluate this product with the
UCC14240Q1EVM-052 evaluation module, available on TI.com for
US$59.
