ADUM5212:  Dual-Channel Isolators with Integrated DC/DC Converter (0/2 Channel Directionality)

Product Details

Product Status:Recommended for New Designs

The ADuM5210/ADuM5211/ADuM5212 are dual-channel digital isolators with isoPower®, an integrated, isolated DC/DC converter. Based on the Analog Devices, Inc., iCoupler® technology, the DC/DC converter provides regulated, isolated power, adjustable between 3.15 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher.

This eliminates the need for a separate, isolated DC/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/DC converter. The result is a small form factor, total isolation solution.

isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations.
