The ADuM6200/ADuM6201/ADuM62021 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 400 mW of regulated, iso-
lated 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 magnetic components of the dc-to-dc converter. The result
is a small form factor, total isolation solution.
The ADuM6200/ADuM6201/ADuM6202 isolators provide two
independent isolation channels in a variety of channel configura-
tions 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.
