Based on the Analog Devices, Inc., i Coupler® technology, the dc-to-dc converter provides up to 500 m W of regulated, isolated power at either 5.0 V from a 5.0 V input supply or 3.3 V from a 3.3 V supply. This eliminates the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The i Coupler chip scale transformer technology is used to isolate the logic signals and the magnetic ponents of the dc-to-dc converter. The result is a small form factor, total isolation solution. The ADu M5401/ADu M5402/ADu M5403/ADu M5404 isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide for more information). 1 1 Figure 3.
