Based on Analog Devices’ iCoupler® technology, the DC/DC converter provides up to 50 mW of regulated, isolated power at +5V. This eliminates the need for a separate isolated DC/DC converter in low-power isolated designs. Analog Devices’ chip-scale transformer iCoupler® technology is used both for the isolation of the logic signals as well as for the DC/DC converter. The result is a small form-factor total-isolation solution. ADuM524x units may be used in combination or with other iCoupler products to achieve greater channel counts. The ADuM524x isolators provide two independent isolation channels...
