500-5011 

500-5011 脚第一组放大器的同相输入端，检测输出电流，与3个0.33R 电阻分压，当电流过大时，分压电阻上的电压超过（2）脚基准电压，（3）脚放大器输出端输出高电平，（3）脚为高电平时，电路进入保护状态。（2）脚为比较器的反相输入端，接（14）脚基准，作比较器的参考电压，外部输入端的控制信号可输入至脚（4）的截止时间控制端（也叫死区时间控制），与脚（1）、（2）、（15）、（16）误差放大器的输入端，其输入端点的抵补电压为120mV，其可限制输出截止时间至小值，大约为初锯齿波周期时间的4%。当13脚的输出模控制端接地时，可获得96%大工作周期，而当(13)脚接制参考电压时，可获得48%大工作周期。如果我们在第4脚截止时间控制输入端设定一个固定电压，其范围由0V至3.3V之间，则附加的截止时间出现在输出上。（5）、（6）脚是一个固定频率的脉冲宽度调制电路，内置了线性锯齿波振荡器，振荡频率可通过外部的一个电阻和一个电容进行调节
