VIORM = 560 V peak
The ADuM3223/ADuM4223 isolators each provide two
ADuM4223 wi de-body, 16-lead SOIC
independent isolated channels. They operate with an input

between the high-side and low-side may be as high as 800 V peak.
Switching power supplies
As a result, the ADuM3223/ADuM4223 provide reliable control
