GENERAL DESCRIPTION
The
quad-channel digital isolators with isoPower®, an integrated,
isolated dc-to-dc converter. Based on the Analog Devices, Inc.,
iCoupler® technology, the dc-to-dc converter provides up to
500 mW of regulated, isolated power at either 5.0 V or 3.3 V from
a 5.0 V input supply, or at 3.3 V from a 3.3 V supply at the power
levels shown in Table 1. These devices eliminate the need for a
separate, isolated dc-to-dc converter in low power, isolated designs.
The iCoupler chip scale transformer technology is used to isolate
the logic signals and for the power and feedback paths in the dc-to-
dc converter. The result is a small form factor, total isolation solution.
The
provide four independent isolation channels in a variety of
channel configurations and data rates (see the Ordering Guide
for more information).
isoPower uses high frequency switching elements to transfer
power through its transformer. Special care must be taken
during printed circuit board (PCB) layout to meet emissions
standards. See the
recommendations.
