Analog Devices ADuM5010/ADuM6010/ADuM521x/ADuM621x isolated DC-to-DC converters

RS Components is stocking isolated DC-to-DC converters from Analog Devices (ADI), claimed to be the smallest in the industry. The ADuM5010, ADuM6010, ADuM521x and ADuM621x use ADI’s isoPower isolated DC-to-DC converter technology to deliver 150 mW of output power while using less board space than other module-based solutions. The ADuM521x and ADuM621x integrate two channels of ADI’s iCoupler data isolation technology to reduce board space by up to 75% compared to optocoupler-based alternatives.

The converters provide designers with a compact, easy-to-implement approach to meeting both isolated power and data requirements. The combination of size and output power addresses the growing space and power constraints engineers must consider when designing control systems, test and measurement equipment, power supplies, motor drives, and other industrial and instrumentation applications.

All of the DC-to-DC converters provide regulated, isolated power, adjustable between 3.15 and 5.25 V. The ADuM5010 and ADuM521x are certified for 2.5-kV rms (1 min) isolation, while the ADuM6010 and ADuM621x are certified for 3.75-kV rms (1 min) isolation with further certification for reinforced insulation per VDE 0884-10. By incorporating iCoupler digital isolator technology, the ADuM521x and ADuM621x reduce component count and simplify and improve design speed, reliability and efficiency by eliminating the need for optocouplers.
