Product Details

This evaluation board is obsolete and no longer recommended. The replacement board is the DC2665B-A.

Demonstration circuit 2665A-A features the LTM4626 µModule® regulator, a high performance, high efficiency step-down regulator. The LTM4626 is a complete DC/DC point-of-load regulator in a thermally enhanced 6.25mm × 6.25mm × 3.87mm BGA package. The LTM4626 has an operating input voltage range of 3.1V to 20V and provides an output current up to 12A. The output voltage is programmable from 0.6V to 5.5V and can be remotely sensed. The stacked inductor design improves thermal dissipation and significantly reduces the package area. Output voltage tracking is available through the TRACK/SS pin for supply rail sequencing. External clock synchronization is available through the SYNC/MODE pin. For high efficiency at low load currents, select DCM mode operation using the MODE jumper (JP7) in less noise sensitive applications. The LTM4626 data sheet must be read in conjunction with this demo manual for working on or modifying DC2665A-A.

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.
