Product Details
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.
Applications
