Analog Devices‘ ADuM347x device is a quad-channel digital isolator with an integrated transformer driver for an isolated DC/DC converter. Based on Analog Devices’ iCoupler technology, the DC/DC converter provides up to 2W of regulated, isolated power at 3.3V to 24V from a 5.0V input supply or from a 3.3V supply.
This eliminates the need for a separate, isolated DC/DC converter in up to 2W isolated designs. The iCoupler 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.
