GENERAL DESCRIPTION  
ADuM5201  
V
OB  
The ADuM5200/ADuM5201/ADuM52021 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 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 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 magnetic  
components of the dc-to-dc converter. The result is a small form  
factor, total isolation solution.

The ADuM5200/ADuM5201/ADuM5202 isolators provide two  
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.
