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.
