Analog Devices isoPower® technology utilizes proprietary iCoupler® chip scale transformers to integrate isolated dc-to-dc converts with data isolation into a single package. This enables designers to implement isolation in designs without the cost, size, power, performance, and reliability constraints found with optocouplers. With more than one billion channels shipped into the field, these magnetically isolated products are a safe, reliable and easy-to-use alternative to optocouplers.
