TI Introduces IsoShield-Based Isolated Power Modules to Boost Power Density for Data Centers and EVs

Texas Instruments has introduced a new family of isolated power modules aimed at increasing power density, efficiency, and safety in applications such as data centers and electric vehicles. The UCC34141-Q1 and UCC33420 devices leverage TI’s proprietary IsoShield multi-chip packaging technology, enabling up to three times the power density of traditional discrete isolated power designs. TI will present these innovations at the Applied Power Electronics Conference, held March 23–26, 2026 in San Antonio.

According to Kannan Soundarapandian, Vice President and General Manager of High Voltage Products at TI, advances in packaging are reshaping the power industry, with power modules leading this shift. IsoShield addresses key design challenges by delivering smaller form factors, improved efficiency and reliability, and faster time to market—underscoring TI’s continued commitment to advancing power semiconductor technologies.

TI’s IsoShield technology combines a high-performance planar transformer with an isolated power stage into a single compact module. It supports functional, basic, and reinforced isolation, making it well suited for distributed power architectures that reduce single points of failure and help meet functional safety requirements. This packaging breakthrough can shrink solution size by up to 70% while delivering up to 2 W of output power, offering compact and robust designs for automotive, industrial, and data center systems requiring reinforced isolation.

As power demands grow in modern data centers and EV platforms, improving power density has become critical. Advanced analog semiconductors are key enablers of more intelligent and efficient operation. With IsoShield, designers can achieve higher power density in constrained spaces, supporting reliable digital infrastructure worldwide. In EV systems, the same advantages allow engineers to develop lighter, more efficient vehicles, extending driving range and enhancing overall performance.
