... V peak IORM GENERAL DESCRIPTION 1 The ADuM524x are dual-channel digital isolators with isoPower™ integrated, isolated power. Based on the Analog Devices, Inc. iCoupler® technology, a chip-scale dc-to-dc converter provides regulated, isolated power which eliminates the need for a separate isolated dc-to-dc converter in low power isolated designs. The Analog Devices chip-scale transformer iCoupler technology is used both for the isolation of the logic signals as well as for the dc-to-dc converter ...
