Texas Instruments ISOW7721 Two-Channel Digital Isolator is a galvanically-isolated digital isolator with an integrated high-efficiency power converter with low emissions. The integrated DC-DC converter provides up to 550mW of isolated power. This feature eliminates the need for a separate isolated power supply in space-constrained isolation designs. If additional power is needed, the Texas Instruments ISOW7721 supports multi-device chaining, increasing the integrated power output to > 1W using two devices in a system.
