原理介绍
LP6401F采用恒定频率、电流模式结构工作。输出电
压返回到VOUT引脚的内部除法器装置。误差放大器将
分离的输出电压与参考电压进行比较，并相应地调整
峰值电感电流
线损补偿
为了补偿充电器线缆电阻造成的输出电压下降，
LP6401F内置线损补偿功能，在不同输出电流条件下，
对输出电压进行补偿，负载电流越大，线损补尝也跟
随增大，
过压保护
LP6401F 输入内置过压保护功能，当输入电压大于
32V 时，输出保护关掉。
热保护
LP6401F 的总功耗受热保护电路的限制。当设备温度
上升到大约+160℃时，该电路关闭输出，使 IC 冷却。
热保护电路能在故障条件下保护装置不受过热损坏。
连续运行 LP6401F 进入热关机状态会降低设备的可靠
性。
