高压HB LED驱动器，集成高边电流检测

MAX16833、MAX16833B、MAX16833C、MAX16833D和MAX16833G为峰值电流控制模式LED驱动器，可配置成boost、buck-boost、SEPIC、反激和高边buck拓扑。亮度调节驱动器设计用于驱动一个与LED串联的外部p沟道管，提供较宽的亮度调节范围。该驱动器能够以较高的PWM频率切换LED电流的通断，不会出现过压和欠压状况。除了PWM调光外，IC还可以通过ICTRL的直流输入提供模拟亮度调节，IC在LED串的高边检测LED电流。 通过RT/SYNC与地之间的单个电阻设置开关频率，工作频率范围为100kHz至1MHz，当外部时钟信号电容耦合至RT/SYNC时 \n• +5V至+65V较宽输入电压范围，提供最高65V的Boost输出 \n• ICTRL引脚用于模拟调光 \n• 200mV满量程、高边电流检测电压 \n• 单通道Boost、SEPIC和Buck-Boost LED驱动器 \n• 可编程工作频率(100kHz至1MHz)，支持同步操作 \n• 增强散热的5mm x 4.4mm、16引脚TSSOP封装，带裸焊盘 \n• 短路、过压和热保护 \n• -40°C至+125°C工作温度范围;
