Tiny isolated DC/DC converter from Analog Devices

Analog Devices, Inc. has unveiled a new small size isolated dc-to-dc converter offering a 5-kV rms (root-mean square) isolation rating in a 10-mm x 10-mm package, the ADuM6000 is a 0.5 watt device that integrates ADI's proprietary iCoupler digital isolation technology and isoPower dc-to-dc converter. Analog Devices says the new digital isolator allows designers to free up valuable circuit-board real estate while eliminating the time-consuming step of securing medical or other safety approvals (such as IEC-60601-1), all at a fraction of the cost of alternative devices, including optocouplers. Safety is a key requirement in medical and industrial designs, and the ADuM6000 protects the device and end users from exposure to voltage levels that could compromise safety and reliability.

Analog Devices also made available the ADuM620x series of dual-channel digital isolators that feature isoPower integrated, isolated dc-to-dc converter technology and 5-kV rms isolation rating. The ADuM620x series includes the ADuM6200, ADuM6201 and ADuM6202 digital isolation products that differ by channel configuration.
