Data Input/Output (I/O) Port Assignments isolators with isoPower, an integrated, isolated dc-to-dc converter. Channel Pin ADuM5210 ADuM5211 ADuM5212 Based on the Analog Devices, Inc., iCoupler technology, the dc-to- V /V 3 V V V IA OA IA OA OA dc converter provides regulated, isolated power that is adjustable V /V IB OB 4 VIB VIB VOB between 3.135 V and 5.25 V. Input supply voltages can range from V /V OA IA 18 VOA VIA VIA slightly below the required output to significantly higher. Popular VOB/VIB 17 V V V OB OB IB voltage combinations and their associated power levels are shown in Table 2. The ADuM5210/ADuM5211/ADuM5212 eliminate the need for a Table 2. Power Levels separate, isolated dc-to-dc converter in low power, isolated designs. Input Voltage (V) Output Voltage (V) Output Power (mW) 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. Rev.
