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
Tabl e 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®.
