Inside iCoupler Technology

ADuM347x PWM Controller and Transformer Driver with Quad-Channel Isolators Design Summary

Systems that require isolation often need to isolate both data paths and power supplies. To simplify such designs and to reduce area, Analog Devices recently released the ADuM347x family of iCoupler digital isolators.
