Isolated DC-DC converters

23 January 2013 Power Electronics / Power Management

Analog Devices has premiered what it claims are the industry’s smallest isolated DC-to-DC converters.

The ADuM5010, ADuM6010, ADuM521x and ADuM621x use proprietary isoPower isolated DC-to-DC converter technology to deliver 150 mW of output power while using less board space than competing module-based solutions.

The ADuM521x and ADuM621x also integrate two channels of iCoupler data isolation technology to reduce board space by up to 75% compared to optocoupler-based alternatives.

The new devices provide regulated, isolated power, adjustable between 3,15 V and 5,25 V. The ADuM5010 and ADuM521x are certified for 2,5 kV rms (1 minute) isolation, while the ADuM6010 and ADuM621x are certified for 3,75 kV rms (1 minute) isolation with further certification for reinforced insulation per VDE 0884-10.
