TI’s integrated transformer module technology helps maximize drive time in hybrid and electric vehicles | Texas News
DALLAS, September 27, 2021 / PRNewswire / – Texas Instruments (TI) (Nasdaq: TXN) today announced the industry’s smallest and most accurate 1.5W isolated DC / DC bias supply module. The UCC14240-Q1 uses proprietary integrated transformer technology that enables designers to cut the size of their power solution in half for use in high voltage environments such as electric vehicles (EVs), hybrid EVs, motor drive systems, and grid-connected inverters. Further information is available at ti.com/UCC14240-Q1-pr.
With the accelerated growth of the EV market, automotive designers are looking for ways to improve efficiency and reliability while reducing the weight of the heaviest part of the EV: the powertrain. To meet the need for smaller, more reliable systems to expand the drive range, engineers are moving to a distributed power supply architecture, a scheme in which each isolated gate driver has a dedicated bias supply. This architecture improves the system’s response to individual errors. If, for example, one bias supply fails, the other bias supplies remain operational, as do their paired gate drivers – and thus help to keep a vehicle safely on the road.
Fully integrated power solutions like the UCC14240-Q1 help engineers take advantage of the distributed architecture. Learn more by reading the technical article “Next Generation Driving EV Systems with a Distributed Architecture in a Bias Supply”.

Extend reach with industry-leading power density and system efficiency
The UCC14240-Q1 offers economies of scale and efficiency that enable higher power density and system efficiency, allowing vehicles to continue driving between charges. The 3.55mm height and small footprint of the UCC14240-Q1 allow designers to reduce the volume of the power solution by up to 50% and pack more power into half the size. The reduction in height also gives engineers full flexibility to place the module on either side of the circuit board.
This dual output power module offers 60% efficiency – twice as much as conventional bias supplies – doubling power density and increasing the range of the vehicle. With an output of more than 1.5 W at an ambient temperature of 105 ° C, the UCC14240-Q1 enables engineers to control insulated gate bipolar transistors (IGBTs), silicon carbide (SiC) and gallium nitride (GaN) switches at high frequencies.
Achieve high CMTI and ultra-low EMI to reduce time to market
Utilizing TI’s integrated transformer technology with a primary-to-secondary capacitance of 3.5 pF, the UCC14240-Q1 can reduce EMI caused by high-speed circuits and conveniently achieve common mode transient immunity (CMTI) greater than 150 V / ns. reach .
With smooth switching, spread spectrum modulation, shielding, and low parasites, the UCC14240-Q1 designs make it easier to meet the Comité International Spécial des Perturbations Radioélectriques (CISPR) 25 and CISPR 32 electromagnetic compatibility standards and reduce time-to-market.
Protect vehicle performance with the industry’s best accuracy over temperature and insulation
The integrated closed-loop control of the UCC14240-Q1 enables an accuracy of ± 1.0% from -40 ° C to 150 ° C. The tight tolerance of the device allows smaller circuit breakers to be used while improving overcurrent protection. Fault monitoring, overcurrent protection, overload protection and overtemperature protection are all fully integrated. The UCC14240-Q1 offers third-party certified 3 kVrms isolation and, due to its extremely light weight and height of 3.55 mm, offers the best vibration resistance in the industry.
Package, availability and prices
The UCC14240-Q1 is available in preproduction quantities from TI in a 36-pin, 12.8mm x 10.3mm x 3.55mm shrink small outline package. The price starts at $ 4.20 in quantities of 1,000 pieces. Engineers can evaluate this product using the UCC14240Q1EVM-052 evaluation module available on TI.com for $ 59.
