DC1669B

查看此评估套件详细信息

Demonstration circuit 1669 features the LTM4627EV μModule regulator, a high‐performance high efficiency step‐down regulator. The LTM4627EV has an operating input voltage range of 4.5V to 20V and is able to provide an output current of up to 15A. The output voltage is programmable from 0.6V to 5V and can be remotely sensed with the internal optional differential remote sensing amplifier. The LTM4627EV is a complete DC‐DC point of load regulator in a thermally enhanced 15mm x 15mm x 4.32mm LGA package requiring only a few input and output capacitors. This regulator is internally compensated and employs constant frequency current mode architecture, enabling a fast transient response and stable control loop over a wide range of output capacitance. It supports frequency synchronization and Burst Mode^® operation for increased light load efficiency. Output voltage tracking is also available through the TRACK/SS pin for supply rail sequencing. The LTM4627 datasheet must be read in conjunction with this demo manual for working on or modifying demo circuit 1669.

优势和特点

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 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.
