GENERAL DESCRIPTION
The ADuM54001 device is a quad-channel digital isolator 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 voltages. This architecture
eliminates 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 the magnetic
components of the dc-to-dc converter. The result is a small form
factor, total isolation solution.
The ADuM5400 isolator provides four independent isolation
channels in two speed grades (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. Refer to the AN-0971 Application Note for details
on board layout recommendations.
