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