UC3843固定频率电流模式控制器之巴公井开创作型号：UC3843A封装：DIP8主要应用：开关电源UC3842 、UC3843 是高性能固定频率电流模式控制器专为离线和直流至直流变换器应用而设计,为设计人员提供只需最少外部元件就能获得本钱效益高的解决方案.这些集成电路具有可微调的振荡器、能进行精确的占空比控制、温度赔偿的参考、高增益误差放年夜器.电流取样比力器和年夜电流图腾柱式输出,是驱动功率MOSFET的理想器件. 其它的呵护特性包括输入和参考欠压锁定,各有滞后、逐周电流限制、可编程输出静区时间和单个脉冲丈量锁存.UC3842A 有16V（通）和10 伏（断）高压锁定门限,十分适合于离线变换器.UC3843A是专为高压应用设计的,高压锁定门限为8.5伏（通）和7.6V（断）.特点:微调的振荡器放电电流,可精确控制占空比. 电流模式工作到500KHZ 自动前馈赔偿锁存脉宽调制,可逐周限流内部微调的参考电压,带欠压锁定年夜电流图腾柱输出欠压锁定,带滞后低启动和工作电流直接与安森美半导体的SENSEFET产物接口引脚图下图是一个显示器的UC3842应用电路图UC3842好坏的判断鉴别方法在国内电子设备傍边,电源PWM控制电路最经常使用的集成电路型号就是UC3842（或KA3842）.也就是因为经常遇到,对它也有一些之得,下面简单介绍一下UC3842好坏的判断方法：在更换完周边损坏的元件后,先不装开关管(MOSFET),加电丈量UC3842的7脚电压,若电压在10-17V间摆荡,其余各脚也分别有摆荡的电压,则说明电路已起振,UC3842基本正常;若７脚电压低,其余接脚无电压或不摆荡,则UC3842已损坏. 在UC3842的7、5脚间外加+17V左右的直流电压,若测8脚有+5V电压,1、2、4、6脚也有分歧的电压,则UC3842基本正常,工作电流小,自身不容易损坏．它损坏的最罕见原因是电源开关管(MOSFET)短路后,高电压从G极加到其6脚而致使其烧毁．而有些机型中省去了G极接地的呵护二极体,则电源开关管(MOSFET)损坏时,UC3842和G极外接的限流电阻必坏．此时直接更换即可. 需要注意的是,电源开关管源极（S极）通常接１个小阻值、年夜功率的电阻作为过流呵护检测电阻．此电阻的阻值一般在0.2-0.6之间,年夜于此值会呈现带不起负载的现象（就是次极电压偏低）. 由于UC3842（KA3842）的工作电压和输出功率均与UC3843（KA3843）相差甚远, 3842系列和3843系列在启动电压和关闭电压方面也存在着较年夜的区别.前者的启动电压为16V,关闭电压为10V;后者的启动电压为8.5V,关闭电压为7.6V.这两个系列的IC不能直接代换.如确有需要用后者代换前者时,要对电路加以改造方可.因此,这一点在维修工作中必需要注意。
