请问,不要用431,光偶用什么IC 好做点,目前这样的IC能做多大W ,用这类IC有什么不好的地方

兄弟,首先你的问题很矛盾,多路电源是不可能不用431,光偶的,多路电源一般采用一路主受控(一般为输出功率较大的那一路),其它各路再去按电压输出的高低,及功率大小平均分配..对于成本的要求是相对的,看你的电源要求指标了,交叉调整率的精度等等.
thanks for your suggestion
as you know .from above description , I would like to design less than 18W with two type of output voltage,not DVD power.
so like this type of power . the cost is to be condsidered first . but not effects basic function . that `s why I mention this requriment.you think illogicality problem ,
