Texas Instruments has introduced two isolated power modules, the UCC34141-Q1 and UCC33420, built around its proprietary IsoShield packaging technology for higher power density in space-constrained designs used in data centers, EVs, industrial systems, and automotive electronics. The core idea is to compress isolated DC/DC functionality into a smaller footprint while still offering isolation options that include reinforced isolation.
The UCC34141-Q1 targets “mid voltage” rails in the 6 V to 20 V range in a 5.85 mm × 7.5 mm × 2.6 mm package. The UCC33420 targets a 5 V “low voltage” rail in a 4 mm × 5 mm × 1 mm package. TI says the IsoShield approach can deliver up to three times higher power density than discrete isolated designs and can shrink solution size by as much as 70%.
IsoShield co-packages a high-performance planar transformer and an isolated power stage in a single multichip package. Along with the density claim, TI ties the technology to “functional, basic, and reinforced” isolation capabilities and frames it as a fit for distributed power architectures. In practical engineering terms, anything that reduces the area and height of isolated point-of-load or intermediate-bus conversion can make board placement and airflow management easier in dense compute trays, but the usual real-world trade is how that integration lands on thermals, derating, and layout constraints when you push for maximum watts in minimum volume.
TI also links IsoShield’s distributed-architecture angle to functional safety, describing it as a way to help avoid single-point failures. For data center power designers, the more immediate takeaway is that integrated isolation can reduce BOM count and layout time when you need isolated rails near sensitive loads, but the density claims will matter most when validated against end-to-end losses and temperature rise in the target enclosure.
Kannan Soundarapandian, vice president and general manager of High Voltage Products at TI, said, “TI’s new IsoShield technology delivers what power engineers need most: smaller solutions with improved efficiency and reliability and a faster time to market.”
TI said preproduction and production quantities of the new isolated power modules are available now on TI.com, along with evaluation modules, reference designs, and simulation models. More details are posted on TI’s IsoShield page at ti.com/IsoShield.
