FB : Voltage feedback pin (电压反馈), the PWM duty cycle is determined by this pin voltage and CS
pin voltage. And the operation mode is controlled by this pin voltage.
CS : Current sense pin (电流检测, 电流取样), connect to sense the MOSFET current.
DEM : Transformer core demagnetization detection (变压器磁芯的重置检测) and output over voltage protection pin. (OVP) 输出过压保护.本回答被网友采纳
开关电源的管理IC的FB,CS,DEM 具体是什么作用啊
FB是电压反馈，CS是电流反馈，DEM就不知道了，最好能把芯片发出来，不同的电路功用也不一样。比如恒流输出电路FB也是电流反馈！

DEM的作用是什么
(Digital Elevation Model,缩写DEM)是一定范围内规则格网点的平面坐标(X,Y)及其高程(Z)的数据集,它主要是描述区域地貌形态的空间分布,是通过等高线或相似立体模型进行数据采集(包括采样和量测),然后进行数据内插而形成的。DEM是对地貌形态的虚拟表示,可派生出等高线、坡度图等信息,也可与DOM或其它专题数据叠加,用于...
