a load switch question about LT3129-1

zhengyun 在 2018-7-1 詢問的問題

Hello,

 

I have a question about an application circuit of LT3129-1:

ltc3129-1_load switch.png

the 2 P channel MOSFETs work as load switch here. I think there is a mistake in the connection: the source pins, s1 and s2, should be connected to the voltage sources 3.3v (dc/dc output) and 3v (battery) respectively. Not the drain pins.

 

Is there any mis-understanding of me?

 

 

thanks,

Zhengyun
