Introduction

The ADuM5210/ADuM5211/ADuM5212 are dual-channel digital isolators with isoPower, an integrated, isolated dc-to-dc converter. 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. 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.
