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 in the data sheet.

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 in the data sheet for additional information.

APPLICATIONS

  • 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)

Product Detail

The ADuM6420A/ADuM6421A/ADuM6422A/ADuM6423A/ADuM6424A 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/ADuM6423A/ADuM6424A data sheet, respectively.

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/EVAL-ADUM6421AURNZ are provided in Figure 4 and Figure 5 in the data sheet. 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 the user guide when using the evaluation boards.
