GENERAL DESCRIPTION

The ADuM520x1 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

with 5.0 V input and 5.0 V output voltage, or 200 mW of power

with 3.3 V input and 3.3 V output voltage. This eliminates the

need for a separate isolated dc-to-dc converter in low power

isolated designs. The Analog Devices chip scale transformer

iCoupler technology is used for the isolation of the logic signals

as well as for the dc-to-dc converter. The result is a small form

factor, total isolation solution.

ADuM520x units can be used in combination with the

ADuM5401, ADuM5402, ADuM5403, ADuM5404, and

ADuM5000 with isoPower® to achieve higher output power

levels and greater channel counts (see the Increasing Available

Power section).

The ADuM520x isolators provide two independent isolation

channels in a variety of channel configurations and data rates

(see the Ordering Guide for options).

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. Refer to the AN-0971 application note for details on

board layout recommendations.
