400mA 单线式相机 LED 充电泵

LTC®3218 是一款低噪声、高电流充电泵 DC/DC 转换器，能够从一个 2.9V 至 4.5V输入以高达 400mA 的电流来驱动高电流 LED。低外部元件数目 (一个跨接电容器、两个编程电阻器以及 VIN 和 CPO 引脚上的两个旁路电容器) 使得 LTC3218 成为小型、电池供电式应用的理想选择。 内置软起动电路可防止在启动时产生过大的浪涌电流。高开关频率允许使用小的外部电容器。一个内置 2s 定时器用于在闪光灯模式期间保护 LED。 输出电流水平由一个外部电阻器来设置。LED 电流采用一个内部高压侧 220mΩ 检测电阻器来调节。自动模式切换功能通过监视充电泵两端的电压、并且仅在 • 低噪声恒定频率操作 \n• 多模式操作：1x 或 2x 升压模式 \n• 自动模式切换 \n• 高输出电流：可从锂离子/锂聚合物电池输入获得 150mA (连续)、400mA (脉动)输出电流 \n• 2s 闪光灯电流超时用于 LED 保护 \n• 自动软起动功能 \n• 输出断接 \n• 无电感器 \n• 220mΩ 内部高压侧电流检测电阻器 \n• 单电阻器编程能力 \n• 纤巧型应用电路 (3mm x 2mm DFN 封装，所有元件的高度均 <1mm);
