• 并联用于高功率应用
• 良好的电流共享
• 所有通道的电流监控引脚
• 可选恒流模式

EVAL-LTM4712-A1Z 评估板是一个电源，可从 5V 至 36V 输入产生 12V、24A（最大值）。EVAL-LTM4712-A1Z 是一种双相解决方案，采用 LTM4712，这是一款高效降压-升压 μ模块® （微模块）稳压器。EVAL-LTM4712-A1Z 在降压和降压-升压模式下可输出 24A 电流，在升压模式下可输出 12A 电流。对于某些 V_IN、V_OUT、频率和热状况，必须进行减额。请参阅性能摘要部分和 LTM4712 数据表以了解更多信息。

EVAL-LTM4712-A1Z 评估板具有可选的恒流功能，可以在负载变化时提供精确的稳定电流。

EVAL-LTM4712-A1Z 评估板使用 400kHz 的默认频率进行了优化。峰值电流模式控制架构可实现轻松的电流共享。默认情况下，LTM4712 在连续电流模式下工作，但可设置为脉冲跳跃模式以在轻负载条件下提高效率。

LTM4712 具有 16mm × 16mm × 8.34mm 球栅阵列封装，这种封装适合通过标准表面安装设备进行自动装配。μModule 封装在模塑衬底顶部采用了电感器，以提高散热能力。

LTM4712 数据手册提供了完整的套件、运行和应用信息说明。在使用或修改 EVAL-LTM4712-A1Z 评估板之前，必须结合本用户指南阅读数据表。

• Parallel for high-power applications
  • Good current sharing
• Current monitoring pin for all channels
• Optional constant current mode

The EVAL-LTM4712-A2Z evaluation board is a power supply generating 12V, 48A (max) from a 5V to 36V input. It is a quad PolyPhase^® solution featuring the LTM4712, a high-efficiency, buck-boost µModule^® (micromodule) regulator. The EVAL-LTM4712-A2Z is capable of 48A in buck and buck-boost modes and 24A in boost mode. Derating is necessary for certain V_IN, V_OUT, frequency and thermal conditions. See the Performance Summary and the LTM4712 data sheet.

The EVAL-LTM4712-A2Z has an optional constant-current feature to deliver a precise, regulated current while the load may vary.

The EVAL-LTM4712-A2Z is optimized using a default frequency of 400kHz. The peak current mode control architecture allows easy current sharing. The LTM4712 operates in continuous current mode by default but can be placed in pulse-skipping mode to optimize efficiency at light loads.

The LTM4712 is offered in a 16mm × 16mm × 8.34mm ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The µModule package features an inductor on top of the molded substrate for improved heatsinking capability.

The LTM4712 data sheet gives a complete description of the device, including operation and application information. The data sheet must be read in conjunction with this evaluation board manual prior to working on or modifying the EVAL-LTM4712-A2Z evaluation board.
