Overview

The ADuM3470/ADuM3471/ADuM3472/ADuM3473/ADuM3474 devicesare quad-channel, digital isolators withan 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. The iCoupler chip-scale transformer technology is used to isolate the logic signals, and the integrated transformer driver withisolated 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 isolationchannels in a variety of channel configurations and data rates.
