GENERAL DESCRIPTION
The ADuM640x1 devices are quad-channel digital isolators with
isoPower®, an integrated, isolated dc-to-dc converter. Based on
the Analog Devices, Inc., iCoupler® technology, the dc-to-dc
converter provides up to 500 mW of regulated, isolated power at
either 5.0 V or 3.3 V from a 5.0 V input supply, or 3.3 V from a
3.3 V supply at the power levels shown in Table 1. This eliminates
the need for a separate, isolated dc-to-dc converter in low power,
isolated designs. The iCoupler chip scale transformer technology
is used to isolate the logic signals and for the magnetic components
of the dc-to-dc converter. The result is a small form factor, total
isolation solution.
The ADuM640x isolators provide four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide for more information).
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. Refer to the AN-0971 application note for board
layout recommendations at www.analog.com.
