GENERAL DESCRIPTION
The ADuM6410/ADuM6411/ADuM64121 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 regulated, isolated
power that is adjustable between 3.15 V and 5.25 V. Popular
voltage combinations and the associated power levels are shown
in Table 1.

Table 2. Data Input/Output Port Assignments
The ADuM6410/ADuM6411/ADuM6412 eliminate the need for a
separate, isolated dc-to-dc converters in low power, isolated designs.
The iCoupler chip-scale transformer technology is used for isolated
logic signals and for the magnetic components of the dc-to-dc
converter. The result is a small form factor, total isolation solution.
