VOB The ADuM5200/ADuM5201/ADuM52021 are dual-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. These
devices eliminate 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. 1 10 07540-001 2-CHANNEL iCOUPLER CORE VIA isoPower uses high frequency switching elements to transfer power
through its transformer. Special care must be taken during printed …
