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 FUNCTIONAL BLOCK DIAGRAMS Figure 1.

The result is a small form factor, isolated solution.
The ADuM5020 and ADuM5028 isolated dc-to-dc converters provide two different package variants: the ADuM5020 in a wide body, 16-lead SOIC_W package, and the ADuM5028 in the space saving, 8-lead, wide body SOIC_IC.
For 5 V input operations, use the ADuM5020-5BRWZ and the ADuM5028-5BRIZ.
