ADuM6420A/21A/22A/21AW/23A/24A DC/DC Converters

ADI's ADuM6420A, ADuM6421A, ADuM6422A, ADuM6421AW, ADuM6423A, and ADuM6424A are members of a quad-channel digital isolator family. They incorporate the isoPower® integrated isolated DC/DC converter based on iCoupler® technology that meets CISPR 32/EN 55032 Class B limits at a full load on a two-layer printed circuit board (PCB) with ferrites. The iCoupler chip scale transformer technology results in a small form factor total isolation solution that provides four independent isolation channels.

The ADuM6420A, ADuM6421A, ADuM6422A, ADuM6421AW, ADuM6423A, and ADuM6424A eliminate the need for a separate isolated DC/DC converter in 500 mW isolated designs. The iCoupler chip scale transformer technology is used for isolated logic signals and the magnetic components of the DC/DC converter. The result is a small form factor total isolation solution.

These isolators provide four independent isolation channels.

The EVAL-ADUM6421ARNZ includes the ADuM6421ABRNZ5 quad-channel digital isolator with an integrated isolated DC/DC converter. Alternatively, the EVAL-ADUM6421AURNZ leaves the isolator position unpopulated to support evaluation of the ADuM6420A, ADuM6421A, ADuM6422A, ADuM6421AW, ADuM6423A, or ADuM6424A.
