产品详情

DC2578A是一款完整的电源链，包括一个热插拔控制器、一个中间总线控制器和六个负载点通道，具有电源系统管理功能。该板演示如何通过LTC4281热插拔控制器和LTC3886降压中间总线控制器(IBC)安全从背板传输电源，并通过调节负载电压的负载点转换器(POL)输出。它全面展示了ADI解决方案的电源管理、协作和安全功能，并展示了如何轻松配置和管理整个电源层次结构。每个稳压电源能够进行时序控制、微调、裕量调节、监控、测量和协作响应故障，并将故障信息记录在非易失性存储器中。此外，板载负载脉冲发生器有助于优化可调LTC3886控制回路响应。整个系统提供的各种状态和遥测信息在一个GUI接口——LTpowerPlay下进行合并和呈现。

产品详情

Demonstration circuit 2278A features the LTC4281 hot swap controller. The LTC4281 is well suited to high power applications because the precise monitoring capability and accurate current limiting reduces the extremes in which both loads and power supplies must safely operate. Non-volatile configuration allows for flexibility in the autonomous generation of alerts and response to faults.

特性和优点

  • Analog Devices has worked closely with Intel PSG to develop verified power solutions that optimize cost, size and efficiency in high performance applications.
  • The validated power solutions include uModules power products that address time and space constraints while delivering high efficiency, reliability, and low noise.
  • The actual power tree represents the best solution at time of design.
  • A recommended power tree has also been included to present the ideal solution at time of Stratix 10 GX SI development kit release. An updated alternate version of the power tree represents the latest solutions available from Analog Devices. For many applications, an intermediate rail is not ideal, so recommendations for an alternate power tree that allows for direct power conversion from 12V input is provided below.
