GENERAL DESCRIPTION

The ADuM50101 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 combinations 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

solution.

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.
