CCM PFC + PWM 组合控制器，线路下垂保护

高度集成的 FAN4800AU 部件设计用于由升压型 PFC 和 PWM 组成的电源。它们仅需要极少的外部元件便可实现各种保护和补偿。它们采用16引脚DIP和SOP封装。PWM可用于电流或电压模式中。在电压模式中，基于PFC输出总线的前馈可减少辅助输出的纹波。要评估 FAN4800AU 能否替换现有的 FAN4800A、FAN4800AS、旧版的 FAN4800 和 ML4800 板，必须在执行微调流程之前完成 6 项任务：1.将RAC电阻从旧值改为更高的电阻值：6 MΩ 改为 8 MΩ。 2.将 RT/CT 引脚从现有值改为 RT= 6.8 kΩ 和 CT= 1000 pF，以具有 fPFC • 引脚对引脚兼容于 ML4800、FAN4800、CM6800 和 CM6800A\n• PWM 可针对电流模式或前馈电压模式运行配置\n• 在一个IC中具有内部同步的前沿PFC和后沿PWM\n• 低工作电流\n• 创新性开关电荷乘法器除法器\n• 平均电流模式，可实现输入电流整形\n• PFC过压和欠压保护\n• PFC反馈开环保护\n• PFC/PWM的逐周期限流保护\n• 启动时序控制和软启动\n• 线电压聚降保护\n• fRTCT= 4 x fPFC= 4 x fPWM;
