The ADuM60101 is an integrated, isolated dc-to-dc converter.
Based on the Analog Devices, Inc., iCoupler® technology, the
dc-to-dc converter provides regulated, isolated power, adjustable
between 3.15 V and 5.25 V. Input supply voltages can range
from slightly below the required output to significantly higher.
Popular combination and their associated power levels are shown
in Table 1.
The iCoupler chip-scale transformer technology is used for isolated
logic signals and for the magnetic components of the dc-to-dc
converter. The result is a small form factor, total isolation
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 AN-0971 Application Note for board layout
