ADUM1420:  Quad Isolated Precision Gate Driver, 0.1 A Output

Product Details


The ADuM1420 is a quad isolated gate driver that employs Analog Devices, Inc. iCoupler® technology to provide independent and isolated high-side and low-side outputs.

In comparison to gate drivers employing high voltage level translation methodologies, the ADuM1420 offers the benefit of true, galvanic isolation between the input and each of the four outputs. Each output can be operated up to ±700 V peak relative to the input, thereby supporting low-side switching to negative voltages. The differential voltage between any two outputs can be as high as 700 V peak.

Applications

  • Plasma display modules
  • FEATURES and BENEFITS

    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.
