GENERAL DESCRIPTION
The
ADuM5200W/ADuM5201W/ADuM5202W
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 500 mW of
regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V input
supply, or 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
ADuM5200W/ADuM5201W/ADuM5202W
isolators
provide two independent isolation channels in a variety of channel
configurations 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.
