Based on the Analog Devices, Inc., i Coupler® 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. mon voltage binations and the associated current output levels are shown in Table 1 through Table 6. The ADu M5020 and ADu M5028 eliminate the need to design and build isolated dc-to-dc converters in applications up to 500 m W. The i Coupler chip scale transformer technology is used for the magnetic FUNCTIONAL BLOCK DIAGRAMS Figure 1. ADu M5020 Functional Block Diagram Figure 2.

The ADu M5020 and ADu M5028 isolated dc-to-dc converters provide two different package variants: the ADu M5020 in a wide body, 16-lead SOIC_W package, and the ADu M5028 in the space saving, 8-lead, wide body SOIC_IC. For 5 V input operations, use the ADu M5020-5BRWZ and the ADu M5028-5BRIZ. For 3.3 V input to 3.3 V output ADu M5020, use the ADu M5020-3BRWZ and the ADu...
