GENERAL DESCRIPTION
The ADuM5410/ADuM5411/ADuM54121 are quad-channel
digital isolators with isoPower®, integrated, isolated dc-to-dc
converters. Based on the Analog Devices, Inc., iCoupler®
technology, the dc-to-dc converters provide regulated, isolated
power that is adjustable between 3.15 V and 5.25 V. Popular
voltage combinations and the associated power levels are shown
in Table 1.

The ADuM5410/ADuM5411/ADuM5412 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 converters. The result is a small form factor, total
isolation solution.
