Isolated DC/DC modules raise power density
Leveraging IsoShield multichip packaging, TI’s isolated power modules deliver up to 3× the power density of discrete devices. The UCC34141-Q1 and UCC33420 reduce solution size by as much as 70% in isolated power designs for applications ranging from data centers to EVs.
IsoShield co-packages a planar transformer and isolated power stage to provide functional, basic, and reinforced isolation. This architecture supports distributed power and helps meet functional safety requirements by avoiding single-point failures.
The UCC34141-Q1 is an automotive-qualified 5-kVRMS DC/DC module for SiC and IGBT isolated gate drivers. It provides 1.5 W typical output at 85°C ambient, with dual outputs set by resistor dividers. A 5.5-V to 20-V input range and adjustable UVLO support EV battery voltages and regulated rails, while VIN transients up to 28 V are tolerated.
The UCC33420 is an industrial 3-kVRMS DC/DC module offering up to 1.5 W of isolated output. It supports a 4.5-V to 5.5-V input and regulates a 5.0-V output with selectable 5.5-V headroom. Multiple protection features are integrated in its 4×5×1-mm package.
The UCC34141-Q1 and UCC33420 are available in preproduction and production quantities, respectively. Evaluation modules are available for both.
