    Hello Weijin, 

    Please specify the VIN for the 3.3V/2A converter.  Have you used WEBENCH for this design to view the various topologies and design types available?  With VIN specified, this would be a good idea to review: https://webench.ti.com/power-designer/switching-regulator .  

    As well, for the LDOs.  I'm assuming they are not from the 3.3V converter, since two of them are 3.3VOUT,

    A block diagram would be very helpful. 

    What do the numbers in the first column represent?  

    Regards, 

    ~Leonard
