LTM4677 - 具数字电源系统管理功能的双通道 18A 或单通道 36A μModule 稳压器
LTM®4677 是一款双通道 18A 或单通道 36A 降压型 μModule® (微型模块) DC/DC 稳压器，其具有通过 PMBus (一种基于 I2C 的开放标准数字接口协议) 实现的远程可配置性及电源管理参数的遥测监察功能。LTM4677 包括快速模拟控制环路、高精度混合信号电路、EEPROM、功率 MOSFET、电感器和支持组件。
LTM4677 的两线式串行接口允许以可编程摆率和排序延迟时间对输出进行裕度调节、调谐以及斜坡上升和下降。输入和输出电流和电压、输出功率、温度、正常运行时间和峰值是可读的。不需要 EEPROM 存储内容的定制配置。在启动时，输出电压、开关频率和通道相位角分配可利用引脚搭接电阻器来设定。可提供 LTpowerPlayTM GUI 和 DC1613 USB 至 PMBus 转换器以及演示套件。
LTM4677 的引脚可与 LTM4676A (双通道 13A) 相兼容，其采用 16mm x 16mm x 5.01mm BGA 封装，并可提供 SnPb 或符合 RoHS 标准的端子涂层。
