Digital Isolators Dual-Channel Isolators with Integrated DC-to-DC Converter (1/1 Channel Directionality)

The ADuM6210 / ADuM6211 / ADuM6212 represent dual-channel digital isolators featuring isoPower, an integrated, isolated dc-to-dc converter. Leveraging Analog Devices, Inc.'s iCoupler technology, the dc-to-dc converter delivers regulated, isolated power with an adjustable range between 3.135 V and 5.25 V. These isolators accommodate input supply voltages ranging from slightly below the required output to significantly higher values, as detailed in Table 2 for popular voltage combinations and their corresponding power levels.

In low-power, isolated designs, the ADuM6210 / ADuM6211 / ADuM6212 negate the necessity for a separate, isolated dc-to-dc converter. The iCoupler chip-scale transformer technology is utilized for both isolated logic signals and the magnetic components of the dc-to-dc converter. The outcome is a compact, all-encompassing isolation solution.

isoPower employs high-frequency switching elements to transfer power through its transformer. Careful attention must be given to printed circuit board (PCB) layout to meet emissions standards. Refer to the AN-0971 Application Note for recommended board layout practices.
