GENERAL DESCRIPTION
The ADuM5200/ADuM5201/ADuM5202¹ 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 ADuM5200/ADuM5201/ADuM5202 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.
