Description
General part information
ADUM3472 Series
TheADuM3470/ADuM3471/ ADuM3472 /ADuM3473/ADuM3474devices are quad-channel, digital isolators with an integrated PWM controller and transformer driver for an isolated DC/DC converter. Based on the Analog Devices, Inc.,iCoupler®technology, the DC/DC converter provides up to 2 W of regulated, isolated power at 3.3 V to 24 V from a 5.0 V input supply or from a 3.3 V supply. This eliminates the need for a separate, isolated DC/DC converter in 2 W isolated designs. TheiCoupler chip-scale transformer technology is used to isolate the logic signals, and the integrated transformer driver with isolated secondary side control provides higher efficiency for the isolated DC/DC converter. The result is a small form factor, total isolation solution.The ADuM347x isolators provide four independent isolation channels in a variety of channel configurations and data rates.APPLICATIONSRS-232/RS-422/RS-485 transceiversIndustrial field bus isolationPower supply startup bias and gate drivesIsolated sensor interfacesProcess controlsAutomotive
