GENERAL 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 the logic signals and the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution.
