GENERAL DESCRIPTION
ADuM3474 devices 1 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., i Coupler?
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 i Coupler 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. The ADuM347x
isolators provide four independent isolation channels in a variety of
