GENERAL DESCRIPTION
The ADuM5401W/ADuM5402W/ADuM5403W1 devices 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
500 mW of regulated, isolated power at 5.0 V (see 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 ADuM5401W-1/ADuM5402W-1/ADuM5403W-1
versions of the isolators provide an upgraded voltage reference
to ensure proper startup under all load conditions (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.
