单级反激和边界模式 PFC 控制器，用于照明

FL6961是通用照明功率控制器，适用于要求功率因数校正的低功率至高功率流明应用。该器件针对临界模式下的反激式或升压转换器而设计。FL6961 提供受控导通时间来调节输出 DC 电压，实现自然功率因数校正。外部开关的最大导通时间可编程设定，以确保AC欠压期间的安全运行。内置创新的多向量误差放大器，以提供快速瞬态响应和精确的输出电压箝位。如果输出反馈环路断开，则内置电路会禁用控制器。启动电流低于 20 μA，工作电流已降至 6 mA 以下。电源电压最高可达 25 V，最大限度地提高应用灵活性。 • 临界模式 PFC 控制器 \n• 低输入电流 THD\n• 受控导通时间 PWM\n• 零电流检测\n• 逐周期限流 \n• 前沿消隐取代 RC 滤波\n• 低启动电流：10 µA（典型值）\n• 低工作电流：4.5 mA（典型值）\n• 反馈开环保护\n• 可编程最大导通时间 (MOT) \n• 输出过压箝位保护\n• 箝位栅极输出电压：16.5V;
