Based on the Analog Devices, Inc., iCoupler® technology, these dc-to-dc converters provide regulated, isolated power that is below CISPR22 Class B limits at full load on a 2‑layer printed circuit board (PCB) with ferrites. Common voltage combinations and the associated current output levels are shown in Table 1 through Table 6. The ADuM5020 and ADuM5028 eliminate the need to design and build isolated dc-to-dc converters in applications up to 500 mW. The iCoupler chip scale transformer technology is used for the magnetic FUNCTI...
