GENERAL DESCRIPTION  
The ADuM6210/ADuM6211/ADuM62121 are dual-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 regulated, isolated  
power that is adjustable between 3.15 V and 5.25 V. Input supply  
voltages can range from slightly below the required output to  
significantly higher. Popular voltage combinations and their  
associated power levels are shown in Table 1.

The ADuM6210/ADuM6211/ADuM6212 eliminate the need  
for a separate, isolated dc-to-dc converter in low power, isolated  
designs. The iCoupler chip-scale transformer technology is used for  
isolated logic signals and for the magnetic components of the dc-  
to-dc converter. The result is a small form factor, total isolation  
solution.  
isoPower uses high frequency switching elements to transfer  
power through its transformer. Take special care during printed  
circuit board (PCB) layout to meet emissions standards. See the  
AN-0971 Application Note for board layout recommendations.
