Hi,Ti工程师:
请帮忙推荐一款电源芯片,具体要求:2.5~3.5V input,4V output,Iout=2A max.可使能控制,关断后vout disconnect.
另外请推荐便于手焊的封装,方便最初阶段调试。最好是SOT类封装,VSON不方便焊接,作为次考虑。
同时请推荐一款LDO,主要作为DC-DC后稳压输出作用,要高电源抑制比,低噪声,高稳态,电流同样要求2A max
急,请帮忙!

Hi
你可以选择TPS61230/TPS61230A, QFN封装,用热风枪焊接,其实比烙铁更简单。(可选择的不多,SOT封装的本身芯片就少)
LDO, 看一下TPS7A83A, TPS7A8300之类。
