ADUM6402:  Quad-Channel Isolators with Integrated DC/DC Converter (2/2 channel directionality)

Информация о продукте

Статус продукта:Производство

The ADuM640x devices are quad-channel digital isolators with isoPower®, an integrated, isolated DC/DC converter. Based on the Analog Devices, Inc., iCoupler® technology, the DC/DC converter provides up to 500 mW of regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V input supply, or 3.3 V from a 3.3 V supply at the power levels shown in Table 1. This eliminates the need for a separate, isolated DC/DC converter in low power, isolated designs. The iCoupler chip scale transformer technology is used to isolate the logic signals and for the magnetic components of the DC/DC converter. The result is a small form factor, total isolation solution.

The ADuM640x isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide for more information).

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 emissions standards. Refer to the AN-0971 application note for board layout recommendations at www.analog.com.


  • isoPower integrated, isolated DC/DC converter
  • Regulated 3.3 V or 5 V output
  • Up to 500 mW output power
  • Quad dc-to-25 Mbps (NRZ) signal isolation channels
  • Schmitt trigger inputs
  • 16-lead SOIC package with 7.6 mm creepage
  • High temperature operation: 105°C
  • High common-mode transient immunity: >25 kV/μs
  • See data sheet for additional features

Solving Isolation Challenges in Power Conversion Applications
This webcast will present solutions to isolation challenges in power conversion applications. Among the topics to be discussed are the limitations of traditional methods of isolation (such as utilization of optocouplers and pulse transformers) vs. more efficient and cost effective solutions that utilize digital isolators. If you are currently using optocouplers and pulse transformers, this is a webcast you should attend.
