GENERAL DESCRIPTION
The ADuM5200W/ADuM5201W/ADuM5202W1 are dualchannel digital isolators with isoPower®, an integrated, isolated dcto-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.
