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 i Coupler chip scale

transformer technology is used to isolate the logic signals and for
the magnetic components of the dc-to-dc converter. The result
is a small form factor, total isolation solution.

tions and data rates (see the Ordering Guide for more information).
iso Power 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
AN-0971 Application Note for board layout recommendations.
