ADuM347x FAMILY: PWM CONTROLLER AND TRANSFORMER DRIVERS WITH QUAD-CHANNEL ISOLATORS
http://www.analog.com/en/interface/digital-isolators/products/overview/over_ADuM347x_Family/resources/fca.html
The ADuM347x Family are quad-channel, digital isolators with an integrated PWM controller and transformer driver for an isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-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-to-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 with isolated secondary side control provides higher efficiency for the isolated dc-to-dc converter.
The result is a small form factor, total isolation solution.
