The ADuM5028 is an isoPower®, integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provide regulated, isolated power that is below CISPR22 Class B limits at full load on a 2-layer PCB with ferrites.
The ADuM5028 eliminates the need to design and build an isolated dc-to-dc converter in 300 mW applications. 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 ADuM5028 isolated dc-to-dc converters provide a space saving 8 pin wide body SOIC.
- 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.
