iCoupler Technology with isoPower - Integrated, Isolated Power
Integrating power supply isolation with data signal isolation, until recently, has been a challenge because of the difficulty of transmitting power from the non-isolated system side to the isolated field side. In the past transferring power across an isolation barrier required a lot of area, with an expensive module or a complex discrete solution.
Analog Devices has addressed this issue by introducing isoPower - an extension of the iCoupler technology. isoPower is a complete and fully integrated isolation solution for power transfer across an isolation barrier using micro-transformers. The iCoupler technology enables both signal and power to be integrated into a single tiny surface mount package with isolation up to 5kV.
Figure 1 shows how our newly released ADuM5401 reduces board space by up to 70% and a cost reduction up to 50%.

Featured Product: ADuM5000 - The World's Smallest DC-to-DC Converter
The recently released ADuM5000 is the world's smallest dc-to-dc converter. Available in a compact 10 mm x 10 mm 16-lead SOIC package, it is a full 40% smaller than the closest competitor's dc-to-dc converter solution. The ADuM5000 provides up to 500 mW of regulated, isolated power at either 5.0V from a 5.0V input supply or 3.3V from either a 3.3V or 5.0 supply. The ADuM5000 can be used in combination with the ADuM520x and ADuM540x isoPower products to achieve higher output power efficiency levels.
The isoPower family of parts offers the designer significant advantages over discrete solutions, such as optocouplers that require an external dc-to-dc converter and often cuts costs by as much as 50%.

ADuM520x/ADuM540x - Two- and Four-Channel, Single-Package Solutions for Data and Power Isolation
The recently released ADuM520x and the ADuM540x families are the second generation of isoPower products released by Analog Devices proprietary iCoupler technology. The two-channel ADuM520x and the four-channel ADuM540x are digital isolators with an isoPower dc-to-dc converter, providing up to 500 mW of isolated power and isolated signal channels within a single package. Like the ADuM5000, the ADuM520x and the ADuM540x devices offer a better choice than discrete solutions using optocouplers and an external dc-to-dc converter in applications such as: industrial field bus isolation, RS-232, RS-422 and RS-485 transceivers and industrial PLCs.
