單級反激和邊界模式 PFC 控制器，用于照明

FL6961是通用照明功率控制器，適用于要求功率因數校正的低功率至高功率流明應用。該器件針對臨界模式下的反激式或升壓轉換器而設計。FL6961 提供受控導通時間來調節(jié)輸出 DC 電壓，實現自然功率因數校正。外部開關的最大導通時間可編程設定，以確保AC欠壓期間的安全運行。內置創(chuàng)新的多向量誤差放大器，以提供快速瞬態(tài)響應和精確的輸出電壓箝位。如果輸出反饋環(huán)路斷開，則內置電路會禁用控制器。啟動電流低于 20 μA，工作電流已降至 6 mA 以下。電源電壓最高可達 25 V，最大限度地提高應用靈活性。 ? 臨界模式 PFC 控制器 \n? 低輸入電流 THD\n? 受控導通時間 PWM\n? 零電流檢測\n? 逐周期限流 \n? 前沿消隱取代 RC 濾波\n? 低啟動電流：10 μA（典型值）\n? 低工作電流：4.5 mA（典型值）\n? 反饋開環(huán)保護\n? 可編程最大導通時間 (MOT) \n? 輸出過壓箝位保護\n? 箝位柵極輸出電壓：16.5V;
