GENERAL DESCRIPTION
The ADuM5000¹ is an isolated dc-to-dc converter based on
the Analog Devices, Inc., iCoupler® technology. The dc-to-dc
converter in this device provides regulated, isolated power in
several combinations of input and output voltages as listed in
Table 1.
The Analog Devices chip scale transformer, iCoupler technology,
transfers isolated power in this dc-to-dc converter with up to
33% efficiency. The result is a small form factor, total isolation
solution.
Higher output power levels are obtained by using the ADuM5000
to augment the power output of ADuM5401, ADuM5402,
ADuM5403, ADuM5404, ADuM520x, and other ADuM5000
iCouplers with isoPower®.

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 recommendations.
