GENERAL DESCRIPTION
The ADuM5210/ADuM5211/ADuM52121 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 ADuM5210/ADuM5211/ADuM5212 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.
