TI launches isolated power modules with IsoShield technology

Texas Instruments (NASDAQ: TXN) announced two new isolated power modules featuring its proprietary IsoShield technology, the UCC34141-Q1 and UCC33420. The company stated the technology enables up to three times higher power density compared to discrete solutions and can reduce solution size by up to 70%.

The modules deliver up to 2W of power and offer functional, basic and reinforced isolation capabilities for automotive, industrial and data center applications. The UCC34141-Q1 measures 5.85mm x 7.5mm x 2.6mm and handles mid voltage (6V-20V), while the UCC33420 measures 4mm x 5mm x 1mm for low voltage (5V) applications.

IsoShield technology copackages a high-performance planar transformer and an isolated power stage within the modules. The technology supports distributed power architecture designed to help manufacturers meet functional safety requirements by avoiding single-point failures.

"TI's new IsoShield technology delivers what power engineers need most: smaller solutions with improved efficiency and reliability and a faster time to market," said Kannan Soundarapandian, vice president and general manager, High Voltage Products at TI.

The modules are part of TI's portfolio of over 350 power modules. Both preproduction and production quantities are available now on TI.com, along with evaluation modules, reference designs and simulation models.

TI showcased the modules at the Applied Power Electronics Conference in San Antonio, Texas, from March 23-26, 2026. The company demonstrated the technology in a 300kW traction inverter reference design and other applications for data centers and automotive systems.
