    产品详情

    演示电路 DC3170A‐A/‐B 采用 LTC7883 和 LTC7051 高电流、高效率的四相降压型转换器。LTC7883 本身是一个带有 PSM 接口的 4 通道、4 相、电压模式降压控制器。LTC7051 是一款 SilentMOS™ 智能功率级，集成了高速驱动器和低 RDS(ON) MOSFET。DC3170A-A/-B 有两种不同的组装类型，具体如下：

    DC3170A-A: 具有四个输出的 LTC7883 + LTC7051 演示板

    • VOA0 = 0.75V/50A
    • VOA1 = 0.9V/50A
    • VOB0 = 1.0V/50A
    • VOB1 = 1.2V/50A

    DC3170A-B:具有单路输出的 LTC7883 + LTC7051 演示板

    • VOUT = 1.0V/200A，4 相

    DC3170A-A/-B 的开关频率为 500kHz，输入电压范围为 7V 至 14V。每个 LTC7051 由 LTC7883 的三态 PWM 输出驱动，而 LTC7051 的电流检测和温度输出由 LTC7883 监控。DC3170A-A/-B 不需要外部串行总线通信即可运行。它使用 LTC7883 非易失性存储器中预先编程的设置。

    如需全面了解该器件的电源系统广泛管理特性，请用电脑下载 LTC7883 软件 LTpowerPlay®，并通过 ADI 公司的 I2C/SMBus/PMBus 加密狗 DC1613A 连接到电路板上。LTpowerPlay 使用户可在运行当中重新配置 LTC7883，并将配置存储在非易失性存储器中，查看电压、电流、温度、故障状态以及其他方面的遥测数据。有关 LTpowerPlay 的更多详细信息和说明，请参阅本手册的 LTpowerPlay 软件 GUI 部分。LTC7883 和 LTC7051 数据手册提供了完整的 IC 操作和应用信息，必须与本演示手册配合阅读。

    产品详情

    Demonstration circuit DC2888A-A/DC2888A-B is an 8-phase single- output, high efficiency, high density, synchronous buck converter with 7 V to 14 V input range. The output can supply up to 400 A maximum load current. The demo board showcases one LTC3888/LTC3888-1 working with eight LTC7051. The LTC3888/ LTC3888-1 is a PMBus-compliant dual loop 8-phase step-down DC/DC controller with digital power system management. LTC7051 is an integrated smart power stage with current sense and temperature monitor. Refer to the LTC3888/LTC3888-1 and LTC7051 data sheets for detailed information.

    DC2888A-A/DC2888A-B powers up to default settings and produces power based on configuration resistors without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter. To fully explore the extensive power system management features of the part, download the GUI software LTpowerPlay ™ on your PC and use Analog Devices' I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows to reconfigure the part on the fly and store the configuration in electrically erasable programmable read-only memory (EEPROM), and view the telemetry of voltage, current, temperature, and fault status.
