Data I/O Port Assignments digital isolators with isoPower, an integrated, isolated dc-to- Channel Pin ADuM6210 ADuM6211 ADuM6212 dc converter. Based on the Analog Devices, Inc., iCoupler VIA/VIA 3 VIA VOA VOA technology, the dc-to-dc converter provides regulated, isolated VIB/VOB 4 VIB VIB VOB power that is adjustable between 3.135 V and 5.25 V. Input supply VOA/VIA 18 VOA VIA VIA voltages can range from slightly below the required output to VOB/VIB 17 V V V OB OB IB significantly higher. Popular voltage combinations and their associated power levels are shown in Table 2. The ADuM6210/ADuM6211/ADuM6212 eliminate the need Table 2. Power Levels for a separate, isolated dc-to-dc converter in low power, isolated Input Voltage (V) Output Voltage (V) Output Power (mW) designs. The iCoupler chip-scale transformer technology is used for 5 5 150 isolated logic signals and for the magnetic components of the dc- 5 3.3 100 to-dc 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.
