Based on the Analog Devices, Inc., iCoupler® technology, the dc-to- V dc converter provides regulated, isolated power that is adjustable IA/VOA 3 VIA VOA VOA V between 3.135 V and 5.25 V. Input supply voltages can range from IB/VOB 4 VIB VIB VOB V slightly below the required output to significantly higher. Popular OA/VIA 18 VOA VIA VIA V voltage combinations and their associated power levels are shown OB/VIB 17 VOB VOB VIB in Table 2. The ADuM5210/ADuM5211/ADuM5212 eliminate the need for a

The iCoupler chip-scale transformer technology is used for isolated 5 5 150 logic signals and for the magnetic components of the dc-to-dc 5 3.3 100 converter. The result is a small form factor, total isolation 3.3 3.3 66 solution. isoPower uses high frequency switching elements to transfer power through its transformer. Take special care during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations. 1 Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329. Other patents are pending.
