说明

MAX1515评估板(EV kit)设计用于评估MAX1515固定关断时间、脉宽调制(PWM)、可源出/吸入电流的降压型DC-DC转换器,优化用于笔记本电脑或亚笔记本电脑的低压、有源端接电源。该评估板缺省工作于DDR模式,VIN允许输入1.3V至3.6V电压,VDD允许输入3.3V作为偏置,VDDQ允许输入2.5V或1.8V作为基准电压。在VOUT端的输出VDDQ / 2电压,可源出或吸入2.5A电流。

在非DDR模式下,可通过引脚选择以下几种VOUT电压:1.5V、1.8V或2.5V,也可以在0.5V至2.7V之间调节VOUT电压。

MAX1515评估板上设置了一些跳线,便于调整反馈(FBSEL0、FBSEL1)、基准选择(REFIN)、DDR模式选择(MODE)、跳脉冲模式(/SKIP)和关断模式(/SHDN)。

关键特性

  • 1.3V至3.6V VIN范围
  • VOUT范围:0.5V至2.7V,可提供2.5A输出电流
  • 可由引脚选择输出电压:1.5V、1.8V或2.5V,输出电流可达2.5A
  • DDR模式使能(/MODE)
  • 强制PWM或跳脉冲模式(/SKIP)
  • 优化工作于500kHz开关频率
  • 关断输入(/SHDN)
  • 电源就绪输出(PGOOD)

应用

  • 有源端接总线
  • 芯片组/图形处理器供电
  • 笔记本电脑DDR存储器终端匹配
