ADUM5212BRSZ

双通道隔离器，集成DC- DC转换器 Dual-Channel Isolators with Integrated DC-to-DC Converters

Product Details

The ADuM5210/ADuM5211/ADuM5212 are dual-channel digital isolators with isoPower®, an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides regulated, isolated power that is adjustable between 3.15 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher. Popular voltage combinations and their associated power levels are shown in Table 2 in the data sheet.

The ADuM5210/ADuM5211/ADuM5212 eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The iCoupler chip-scale transformer technology is used for isolated logic signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation 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.
