产品详情

演示电路 2268A-F 是 PCB 占板面积紧凑型 (1.5 英寸 × 1.2 英寸) 高效率、高密度、双通道 8A 开关模式降压型电源。它采用了 LTM4630A μModule® 稳压器。输入电压范围为 4.5V 至 15V。输出电压可编程范围为 0.6V 至 5.3V。DC2268A-F 每个通道可提供高达 18A (最大值) 的电流。如数据手册中所述，对于某些 VIN、VOUT 和热状况，必需进行输出电流降额。在重负载条件下，该演示板以连续导通模式运行。为了在低负载电流下实现高效率，在对噪声敏感的应用中，电阻跳线 (R1/R2) 选择脉冲跳跃模式，而在噪声不太敏感的应用中，则选择突发模式 (Burst-Mode®)。对于带可选跳线电阻器的单路 36A 输出解决方案，两个输出可以并联连接。该演示板使用户可通过 TRACK/SS 引脚设置其输出的斜坡上升和下降方式。远端输出电压检测可用于改善负载点上的输出电压调节。在对噪声敏感的应用中，可选的输入电感器 L1 可降低 EMI 噪声。DC2268A 可容易地插入边缘连接器以进行测试和调试。由于具有这些特性，加上 LTM4630A 可采用紧凑的 16mm × 16mm × 4.41mm LGA 封装，因而使其成为许多高密度负载点调节应用的理想选择。必须将本演示手册与 LTM4630A 数据手册配合阅读，以便处理或修改 DC2268A-F。

产品详情

Demonstration circuit 2152A features the LTM4630AEV high efficiency, high density, dual 18A, switch mode step-down µModule regulator. The input voltage is from 6V to 15V, and the output voltages are set at 3.3V and 5V, but are programmable from 0.6V to 5.3V. The DC2152A can deliver up to 18A maximum from each channel. The two outputs can be connected in parallel for a single 36A output solution with optional jumper resistors. ±3% transient accuracy can be achieved with a 25% load step.


Output current derating is necessary for certain VIN, VOUT, and thermal conditions. Its many features and its compact 16mm × 16mm × 4.41mm LGA package make the LTM4630AEV ideal for use in many high-density point-of-load regulation applications.

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 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.
