Analog Devices Inc. ADuM5020 & ADuM5028 isoPower DC-to-DC Converters

Analog Devices Inc. ADuM5020 and ADuM5028 isoPower® DC-to-DC Converters are low-emission, isolated DC-to-DC Converters based on iCoupler® technology. The ADuM5020 and ADuM5028 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-DC Converters for applications up to 500mW. 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, ideal for space constrained applications.

The ADuM5020 and ADuM5028 are available in two different package variants. The ADuM5020 is offered in a wide body, 16-lead SOIC_W package, and the ADuM5028 is offered in a compact 8-lead, wide body SOIC_IC.
