Based on the AnalogDevices, Inc., iCoupler? technology, the DC-to-DC converter providesregulated, isolated power that meets CISPR 32/EN 55032Class B limits at full load on a 2-layer printed circuit board (PCB)with ferrites. Popular voltage combinations and the associatedoutput current levels are listed in Table 1.The ADuM6221A eliminates the need for a separate, isolatedDC-to-DC converter in 500 mW, isolated designs. The iCoupler chipscale transformer technology is used for isolated logic signals andfor the magnetic components of the DC-to-DC converter. The resultis a small form factor and total isolation solution.The ADuM6221A isolators provide two independent isolation channels(for more details, see the Pin Configurations and FunctionDescriptions section).Applications RS-232 transceivers Power supply start-up bias and gate drives Isolated sensor interfaces Automotive on-board charger (OBC) and DC-to-DC Industrial programmable logic controllers (PLCs)
