Low Emission 500 mW Isolated DC-to-DC Converter

The ADuM5020 is an isoPower®, integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides 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 eliminates the need to design and build an isolated dc-to-dc converter in 500 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 ADuM5020 isolated dc-to-dc converter is available in a wide-body 16-lead SOIC package.
