GENERAL DESCRIPTION
The ADuM520x1 are dual-channel digital isolators with
isoPower, an integrated, isolated DC/DC converter. Based on
Analog Devices’ iCoupler® technology, the DC/DC converter
provides up to 500 mW of regulated, isolated power at either
5.0V from a 5.0V input supply or 3.3V from a 3.3V or 5.0V
supply. This eliminates the need for a separate isolated DC/DC
converter in low-power isolated designs. Analog Devices’ chip-
scale transformer iCoupler technology is used both for the
isolation of the logic signals as well as for the DC/DC converter.
The result is a small form-factor total-isolation solution.
ADuM520x units may be used in combination with ADuM540x
and ADuM5000 with isoPower to achieve higher output power
levels and greater channel counts.
The ADuM520x isolators provide two independent isolation
channels in a variety of channel configurations and data rates
(see Ordering Guide).
