The ADuM6020/ADuM60281 are isoPower®, integrated, isolated dc-to-dc converters. 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 4 in the data sheet.
The ADuM6020/ADuM6028 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 components of the dc-to-dc converter. The result is a small form factor, isolated solution.
The ADuM6020/ADuM6028 isolated dc-to-dc converters provide two different package variants: the ADuM6020 in a wide-body, 16-lead SOIC_IC package, and the ADuM6028 in the space-saving, 8-lead, wide-body SOIC_IC package. For 5 V input operations, use the ADuM6020-5BRIZ and the ADuM6028-5BRIZ. For 3.3 V input to 3.3 V output operations, use the ADuM6020-3BRIZ and the ADuM6028-3BRIZ. See the Pin Configuration and Function Descriptions section and the Ordering Guide in the data sheet for more information.
