Other Parts Discussed in Thread: LMP8603 按照规格书,LMP8603的默认放大倍数是100倍,当offset脚接Vs的时候,空载输出是Vs/2.
但是当我按照式样书,通过在A1,A2端串接10K对地电阻将放大倍数调节至10倍的时候,这时候空载输出却变成了0V,不是Vs/2了。这是为什么?

我看TPS6103*的手册,标题写可以开关4A(TPS6103x 96% Efficient Synchronous Boost Converter With 4A Switch),
但后面说5V时输出电流时1A(It provides high efficient power conversion and is capable of delivering output currents up to 1 A at 5 V at a supply voltage down to 1.8 V.)
这芯片到底是输出1A…
