VID Figure 2. ADuM5401W The ADuM5401W/ADuM5402W/ADuM5403W1 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 5.0 V (see Table 1).
These devices eliminate the need for a separate, isolated dc-todc 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. VIA
