高压, 4通道 LED 驱动器

RT8577A 是4通道的 LED 驱动器，每个通道的输出能力高达 120mA 。它是一个输入电压范围为 5.5V~40V 、可通过 RT 引脚对工作频率进行 200kHz~2.1MHz 调节的电流模式 Boost 转换器。\n\n其 PWM 输出电压调节回路选择 LED 串电压最高的通道的 LED 引脚作为电压回馈点并使之稳定在 0.6V ，藉此确保各通道 LED 串电压不一致的情况下仍能获得稳定的电流输出。RT8577A 自动对各 LED 串进行开路、断路检测并自动断开有问题通道的电路连接以避免输出电压 V_OUT 出现过压状况。各 LED 通道的电流可通过一只电阻进行 • 宽输入电压范围： 5.5V~40V\n• 可程序设计输出电流\n• 外部调光控制\n• 自动 LED 开路、短路保护以防范输出过压\n• 可调过压保护\n• 热关机保护\n• AEC-Q100 Grade 3认证\n• 符合 RoHS 规范，不含卤素;
