GENERAL DESCRIPTION

V
V
V
The ADuM5401W/ADuM5402W/ADuM5403W1 devices 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 5.0 V. This eliminates  
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 ADuM5401W/ADuM5402W/ADuM5403W isolators  
provide four independent isolation channels in a variety of  
channel configurations and data rates (see the Ordering Guide  
for more information).  
Figure 4. ADuM5403W  
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. Refer to the AN-0971 application note for board  
layout recommendations at www.analog.com.
