GENERAL DESCRIPTION

The ADuM6420A/ADuM6421A/ADuM6422A/ADuM6423A/ ADuM6424A1 are quad-channel digital isolators with an isoPower?, integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler? technology, the dc-to-dc converter provides regulated, isolated power that meets CISPR 32/EN 55032 Class B limits at a full load on a 2-layer printed circuit board (PCB) with ferrites. Popular voltage combinations and the associated output current levels are listed in Table 1.

The ADuM6420A/ADuM6421A/ADuM6422A/ADuM6423A/ ADuM6424A eliminate the need for a separate, isolated dc-to-dc converter in 500 mW, isolated designs. The iCoupler chip scale transformer technology is used for isolated logic signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution.

The ADuM6420A/ADuM6421A/ADuM6422A/ADuM6423A/ ADuM6424A isolators provide four independent isolation channels (see the Pin Configurations and Function Descriptions for additional information).
