GENERAL DESCRIPTION
The ADuM5400
1
device is a 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
either 5.0 V from a 5.0 V input supply or 3.3 V from a 3.3 V supply.
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 the magnetic components of the
dc-to-dc converter. The result is a small form factor, total isolation
solution.
The ADuM5400 isolator provides four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide for more information).
