高压、350mA、高亮度LED驱动器，提供模拟及PWM调光控制

MAX16804电流调节器可工作在5.5V至40V输入电压范围内，提供35mA至350mA电流来驱动一串或多串高亮度LED (HB LED)。MAX16804输出电流的大小通过一个与LED串联的外部检流电阻来调节。双模式DIM引脚和片上200Hz斜坡发生器使用模拟或PWM控制信号来实现PWM亮度调节。给亮度控制输入端DIM施加模拟控制信号允许实现“theater”式亮度控制效果。快速的开通/关闭时间允许使用宽范围的PWM工作，波形整形电路可以使EMI最小化。差分电流检测输入提高了LED电流精度和噪声抑制能力。MAX16804非常适合要求高压输入的应用，并能够承受高达45V的汽车抛负载事件。片上 \n• 灵活的亮度控制：模拟或PWM控制信号用于PWM或“theater”式亮度控制 \n• 片上200Hz斜坡发生器 \n• 接收外部PWM信号(高达2kHz) \n• 5.5V至40V工作电压范围 \n• 可调LED电流(35mA至350mA) \n• 3% LED电流精度 \n• 高压DIM引脚(高达40V) \n• 内置调整元件，低压差(典型值0.5V) \n• 额外的片上+5V稳压输出，具备2mA电流容量 \n• 差分LED电流检测 \n• 200mV低电流检测基准，降低了功耗 \n• 波形整形电路使脉冲电流具有平滑的边沿，从而降低了PWM亮度控制时的EMI \n• 输出短路;
