請(qǐng)問(wèn),不要用431,光偶用什么IC 好做點(diǎn),目前這樣的IC能做多大W ,用這類(lèi)IC有什么不好的地方

1:除了電壓精度不好搞啊..?還有什么其它的問(wèn)題?有什么好IC好推薦的?我現(xiàn)在是做小W的10W,15w,兩路輸出,三路輸出..需要考慮那些難題啊,體積,成本,,,,?2:對(duì)于多路輸出這一點(diǎn),有那些方面要注意啊?各位幫我出下好的建議啊謝謝啊
兄弟,首先你的問(wèn)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(duì)于成本的要求是相對(duì)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 ,
