GENERAL DESCRIPTION
The ADuM6210/ADuM6211/ADuM62121 are dual-channel digital isolators with isoPower®, an integrated, isolated dc-todc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides regulated, isolated power that is adjustable between 3.135 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher. Popular voltage combinations and their associated power levels are shown in Table 2.
The ADuM6210/ADuM6211/ADuM6212 eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The iCoupler chip-scale transformer technology is used for isolated logic signals and for the magnetic componen...
