ID  
The ADuM5401/ADuM5402/ADuM5403/ADuM54041 are  
quad-channel digital isolators with isoPower®, an integrated,  
isolated dc-to-dc converter. Based on the Analog Devices, Inc.,  
iCoupler® technology, the dc-to-dc converter provides up to  
500 mW 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 iCoupler chip scale transformer technology is used  
to isolate the logic signals and for the power and feedback paths  
in the dc-to-dc converter. The result is a small form factor, total  
isolation solution.

The ADuM5401/ADuM5402/ADuM5403/ADuM5404 isolators  
provide four independent isolation channels in a variety of  
channel configurations and data rates (see the Ordering Guide  
for more information).

isoPower 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. See the AN-0971 Application Note for board layout  
recommendations.
