ADUM5404:  Quad-Channel Isolators with Integrated DC/DC Converter

Product Description

The ADuM5401/ADuM5402/ADuM5403/ADuM54041 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 either 5.0 V from a 5.0 V input supply or 3.3 V from a 3.3 V supply. This 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 both the logic signals and the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution.

The ADuM5401/ADuM5402/ADuM5403/ADuM5404 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. Refer to Application Note AN-0971 for details on board layout considerations.
