Evaluating the LTC3888/LTC3888-1, 8-Phase, Single Output Synchronous Buck Converter with Power System Management
Evaluating the LTC3888/LTC3888-1, 8-Phase, Single Output Synchronous Buck Converter with Power System Management
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.

LTC3888-1演示板 | 具有电源系统管理功能的8相、双输出同步降压转换器
产品详情
演示电路2652A-B是一款8相双路输出、高效率、高密度、同步降压转换器，具有7V至14V输入电压范围。具有1V输出时，每个输出可提供高达120A的最大负载电流。该演示板用于演示LTC3888-1，它是一款具有数字电源系统管理功能的PMBus兼容双环路8相降压DC/DC控制器。LTC3888-1用于和DrMOS器件配套使用，后者提供输出电流检测和温度监控器。有关更多详细信息，请参见LTC3888-1数据手册。
DC2652A-B上电至默认设置并基于配置电阻（或使用其非易失性存储器中的设置）产生电源，无需任何串行总线通信。这样可轻松评估DC/DC转换器。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GUI软件LTpowerPlay™，并通过ADI 的I2C/SMBus/PMBus加密狗DC1613A连接到板上。LTpowerPlay允许用户重新配置联机器件，将配置存储在EEPROM中，并查看电压、电流、温度和故障状态的遥测功能。
