GENERAL DESCRIPTION
The
Analog Devices, Inc., iCoupler® technology. The dc-to-dc converter
in this device provides regulated, isolated power in several combi-
nations 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
31% efficiency. The result is a small form factor, total isolation
solution.
Higher output power levels are obtained by using the ADuM6000
to augment the power output of the ADuM5401, ADuM5402,
ADuM5403, ADuM5404, ADuM520x, and
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
recommendations.

... In many cases, the approved working voltage is higher than the 50-year service life voltage. Operation at these high working voltages can lead to shortened insulation life in some cases. The insulation lifetime of the ADuM6000 depends on the voltage waveform imposed across the isolation barrier. The iCoupler insulation structure degrades at different rates depend- ing on whether the waveform is bipolar ac, unipolar ac ...
