ADI ADUM5401WCRWZ-1RL

磁耦合42500Vrms

Overview

The ADuM5401/ADuM5402/ADuM5403/ADuM5404 arequad-channel digital isolators with isoPower®, an integrated,isolated dc-to-dc converter. Based on the Analog Devices, Inc.,iCoupler® technology, the dc-to-dc converter provides up to 500 mW of regulated, isolated power at either 5.0 V or 3.3 Vfrom a 5.0 V input supply, or at 3.3 V from a 3.3 V supply at thepower levels shown in Table 1. These devices eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The iCoupler chip scale transformer technology is used to isolate the logic signals and for the power and feedback pathsin the dc-to-dc converter. The result is a small form factor, total isolation solution.

isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissionsstandards. See the AN-0971 Application Note for board layout recommendations.
