GENERAL DESCRIPTION
The ADuM6400/ADuM6401/ADuM6402/ADuM6403/
ADuM64041 are quad-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 400 mW of regulated, isolated power at either 5.0 V or 3.3 V
from a 5.0 V input supply, or at 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 ADuM6400/ADuM6401/ADuM6402/ADuM6403/
ADuM6404 isolators provide four 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.
