Analog Devices Introduces Industry’s Smallest Isolated DC-to-DC Converter
- New iCoupler® digital isolation device with isoPower® dc-to-dc converter technology delivers 50 percent
reduction in size and cost compared to optocoupler-based solutions.
Analog Devices, Inc. (ADI), a global leader in
high-performance semiconductors for signal-processing applications, is expanding its extensive portfolio of
digital isolation products with the industry’s smallest isolated dc-to-dc converter. Offering a 5-kV rms
(root-mean square) isolation rating in a 10-mm × 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. 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.

The ADuM6000 digital isolator enables designers to reduce the form factor of their system
module or to maintain the same form factor even as they add more features and functions. With alternate solutions,
such as optocouplers and separate, isolated dc-to-dc converters, it may not be possible to add new functionality
to existing system modules.
Also now available are 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
ADuM6202 digital isolation products that differ by channel configuration.
Availability, Pricing and Complementary Components
In some designs requiring USB (universal serial bus) isolation and isolated power, the
ADuM4160 USB isolator can be used together with the ADuM6xxx devices.
With more than 450 million channels deployed throughout the industry, ADI’s
proven iCoupler technology is based on chip-scale transformers, rather than the LEDs and photodiodes used in
optocouplers. Transformers can support higher data rates and lower power consumption, and are more stable over
life as compared to LEDs and photodiodes. By fabricating the transformers directly on-chip using wafer-level
processing, iCoupler channels can be integrated with each other and other semiconductor functions at low cost.
iCoupler transformers are planar structures formed from CMOS and gold metal layers. A high breakdown polyimide
layer underneath the gold layer insulates the top transformer coil from the bottom. CMOS circuits connected to the
top coil and bottom coil provide the interface between each transformer and its external signals. For more on

isoPower® DC-to-DC Converter ADI’s isoPower integrated, isolated dc-to-dc converter
uses the same chip-scale transformer technology, but instead of transmitting data, isoPower employs switches,
rectifiers, and regulators to generate power that is isolated to the same degree as the data channels.
