IsoShield™ packaging technology

The future of isolated power

TI’s proprietary IsoShield™ multichip packaging technology integrates a high-performance planar transformer with an isolated power stage for an all-in-one system-in-package (SiP) solution that enables the highest levels of power density for isolated bias supplies with options for different certified isolation levels.

Benefits:

Deliver up to 3x higher power density than discrete solutions
Help reduce solution size by up to 70% compared to discrete solutions
Achieve higher efficency and lower temperature rise compared to existing modules
Achieve higher levels of safety and reliability
Help reduce design time with easy-to-use devices.
