請問,不要用431,光偶用什么IC 好做點,目前這樣的IC能做多大W ,用這類IC有什么不好的地方

兄弟,首先你的問題很矛盾,多路電源是不可能不用431,光偶的,多路電源一般采用一路主受控(一般為輸出功率較大的那一路),其它各路再去按電壓輸出的高低,及功率大小平均分配..對于成本的要求是相對的,看你的電源要求指標(biāo)了,交叉調(diào)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 ,
