RS-232 transceivers Power supply start-up bias and gate drives Isolated sensor interfaces Automotive on-board charger (OBC) and dc to dc Industrial programmable logic controllers (PLCs) 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-todc 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. 1 The ADuM6420A/ADuM6421A/ADuM6422A/ADuM6423A/ ADuM6424A isolators provide four independent isolation channels (see the Pin Configurations and Function Descriptions for additional information).

PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS. 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/ADuM6423A/ ADuM6424A data sheet. The ADuM6420A/ADuM6421A/ADuM6422A/ADuM6423A/ ADuM6424A 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. Radiated emissions test plots of the EVAL-ADUM6421ARNZ/EVALADUM6421AURNZ are provided in Figure 4 and Figure 5. 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, ADuM6422A, ADuM6423A, or ADuM6424A. Full specifications for the ADuM6420A/ADuM6421A/ ADuM6422A/ADuM6423A/ADuM6424A are available in the ADuM6420A/ADuM6421A/ADuM6422A/ADuM6423A/ ADuM6424A data sheet, which must be consulted in conjunction with this user guide when using the evaluation boards.
