Product Details

The DC2023A is a demonstration system for the LTM2987 16-channel I2C/SMBus/PMBus power system manager with EEPROM. The LTM2987 monitors and controls 16 power supply rails. The DC2023A demonstrates the ability of the LTM2987 to sequence, trim, margin, supervise, monitor, and log faults for 16 power supply rails. Each power supply channel’s output voltage is monitored and the LTM2987 monitors its own internal die temperature.

Features and Benefits

  • 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 PCIe 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 an alternate power tree that allow for direct power conversion from 12V input is provided below.
