GENERAL DESCRIPTION
The
ADuM6210/ADuM6211/ADuM6212
1
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
The
ADuM6210/ADuM6211/ADuM6212
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.
