GENERAL DESCRIPTION
The ADuM5401W/ADuM5402W/ADuM5403W1 devices are quad-channel digital isolators with
V V
isoPower®, an integrated,
IA OA 3 14
isolated dc-to-dc converter. Based on the Analog Devices, Inc.,
V ADuM5402W IB VOB 4 13 V
iCoupler® technology, the dc-to-dc converter provides up to
OC VIC 5 12
500 mW of regulated, isolated power at 5.0 V (see Table 1).

These devices eliminate the need for a separate, isolated dc-to- 08758- dc converter in low power, isolated designs. The iCoupler chip Figure 3. ADuM5402W 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.
