Digital isolator integrates DC/DC converter

TI’s ISOW7841 reinforced digital isolator integrates a DC/DC converter that provides up to 650 mW of isolated power, while offering 80% higher efficiency than most integrated devices, according to the manufacturer. This quad-channel isolator reduces device operating temperature by up to 40°C, enabling higher power delivery, higher channel count, and longer system lifetime.

By combining 5000 V_RMS reinforced isolation and DC/DC conversion in a single package, the ISOW7841 eliminates the need for a separate isolated power supply, minimizing both board space and BOM cost. Additionally, a working voltage of 1 kV_RMS helps improve system reliability and life expectancy.
