Подробнее о продукте

The ADuM6420A/ADuM6421A/ADuM6422A devices integrate four iCoupler® on-off keying (OOK) digital isolation channels and iCoupler chip scale isoPower® transformer technology.

This iCoupler transformer technology enables a small form factor integrated, reinforced isolated signal and power solution, in applications requiring up to 500 mW of isolated power.

Available dc-to-dc converter supply configurations and maximum available power at the elevated ambient temperatures are specified in the ADuM6420A/ADuM6421A/ADuM6422A data sheet.

The ADuM6420A/ADuM6421A/ADuM6422A devices provide regulated, isolated power that meets CISPR 32/EN 55032, Class B limits at full load on a 2-layer printed circuit board (PCB) with ferrite beads. All devices in the family include the same isolated dc-to-dc converter and are differentiated by directional digital channel configurations.

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

Full specifications for the ADuM6420A/ADuM6421A/ADuM6422A are available in the ADuM6420A/ADuM6421A/ADuM6422A data sheet, which must be consulted in conjunction with the user guide when using the evaluation boards.
