The ADuM5020 and ADuM50281 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.
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 components of the dc-to-dc converter. 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. For 3.3 V input to 3.3 V output ADuM5020, use the ADuM5020-3BRWZ and the ADuM5028- 3RIZ. See the Pin Configuration and Function Descriptions section and the Ordering Guide for more information.
- RS-485/RS-422/CAN transceiver power
- Power supply startup bias and gate drives
- Isolated sensor interfaces

Evaluation Kits (1)
The EVAL-ADUM5028EBZ allows the user to evaluate the ADuM5028 isolated power solution. The ADuM5028 eliminates the need to design and build an isolated dc-to-dc converter in 60 mA applications. The iCoupler® chip scale transformer technology is used for the inductive component of the dc-to-dc converter. The result is a small form factor, isolated solution.
Based on the Analog Devices, Inc., iCoupler technology, the ADuM5028 dc-to-dc converter provides regulated, isolated power that is well below CISPR22 Class B limits when at full load on a 2-layer printed circuit board (PCB) with ferrites.
Full specifications of the ADuM5028 can be found in the ADuM5028 data sheets available from Analog Devices, and must be consulted in conjunction with this user guide when using the evaluation board.
