(UTC78D33的datasheet表明输入最高的电压是18.5V),会不会功耗太大烧了芯片,如果采用15V-5V-3.3V的形式(先通过78D05降到5V,在78D

在datasheet上面写着TLC2254的工作电压在4V,现在改用3.3V单电源供电,编制3.3/2 这样芯片是否可以正常工作

起因: 玩nas+软路由,m2+无线网卡+板载各种芯片(网卡)等对3.3v需求大,估算需求约20a,nas用的是flex电源,flex电源3.3v基本都只有10-15a,目前用的电源3.3v只有

按照 TPS61221的数据手册,其输入电压范围为0.7V-5.5V,当输入电压大于3.3V时,其输出电压不再稳压为3.3V,当输入电压为5V时,其输出为4.7

在是用AD9218的时候,VD和VDD都是用的3.3V,两组电源同时上电没有问题,但是VD3.3V先上电,VDD3.3V后上电,反复几次就会烧掉AD9218(完全可以重现)。而
