Based on the Analog Devices, Inc., i Coupler® technology, the dc-to-dc converter provides up to 400 m W of regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V input supply, or at 3.3 V from a 3.3 V supply at the power levels shown in Table 1. These devices eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The ADu M6400/ADu M6401/ADu M6402/ADu M6403/ ADu M6404 isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide for more information). iso Power uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards.
