LTC3207

600mA 通用型多输出 LED/CAMdrive

 

peculiarity

  • 低噪声、多模式充电泵 (1x、1.5x、2x) 提供了高达91% 的效率
  • Slew rate-limited switching reduces conducted and radiated noise (EMI)
  • Up to 600mA total output current
  • 具 64 级线性亮度控制能力的 12 个 28mA 通用电流源
  • 具 16 级线性亮度控制能力和两秒高电流安全定时器的 425mA CAM (相机) LED 电流源
  • 采用两线式I2CTMInterface for independent turn-on/off, brightness level, flicker, and grayscale control for each current source
  • Internal current reference
  • 提供了两个 I2C 地址 (LTC3207 00110110,LTC3207-1 00110100)
  • Configurable ENU pins for asynchronous LED turn-on/off-control
  • Automatic or forced mode switching
  • An internal soft-start feature limits inrush current
  • Short circuit/thermal protection
  • 4mm x 4mm 24 引脚 QFN 塑料封装
  • description

    LTC®3207/LTC3207-1 是高集成度多显示屏 LED 驱动器。该器件包括一个高效率、低噪声充电泵,用于为 12 个通用LED 电流源和一个相机 LED 电流源供电。LTC3207/LTC3207-1 只需 5 个小陶瓷电容器即可构成一个完整的 LED 电源和电流控制器。此外,还提供了两个 I2C 地址。

    显示屏电流由一个内部精准电流基准来设定。所有通用电流源的独立调光、接通/关断、闪烁和灰度等级控制均通过 I2C串行接口来实现。可使用 6 位线性 DAC 来调节每个通用LED 电流源的亮度电平。CAM 电流源具有一个用于调节亮度的 4 位线性 DAC。

    LTC3207/LTC3207-1 充电泵根据 LED 电流源两端的电压来优化效率。该器件在1x模式中上电,并将在任一被使能的LED 电流源开始进入压降状态时自动切换至升压模式。第一个压降将把IC转换至 1.5x 模式,随后的一个压降则把LTC3207/LTC3207-1 切换至 2x 模式。当某个数据寄存器通过 I2C 端口更新时,该器件将复位至 1x 模式。
