The ADuM5210/ADuM5211/ADuM52121 are dual-channel digital isolators with isoPower®， an integrated， isolated dc-to-dc converter. Based on the Analog Devices， Inc.， iCoupler® technology， the dc-todc converter provides regulated， isolated power that is adjustable between 3.15 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 ADuM5210/ADuM5211/ADuM5212 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 components of the dc-to-dc converter. The result is a small form factor， total isolation solution. isoPower uses high frequency switching elements to transfer power through its transformer. Take special care during printed circuit board （PCB） layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations.
