regarding the tps54240&tps54340

Dear sir,

                 .   As we discussed earlier i have designed  the schematic as well as board layout. Here i attached schematic & board files for your reference schematic and board.zipschematic and board.zip,send your feedback.

I have  query,

1.  Now,  i have used different voltage power sources and in layout common GND filling method .whether i need to use to give isolated GND for  each voltage source, could you able to give suggestion?

          2. could you send

                  a) shape to shape clearance for 2A net
2705.ti.zip2705.ti.zip

                  

         3.As per TI datasheet design layout  guidelines, 

"Power Supply Recommendations
The design of the device is for operation from an input voltage supply range between 3.5 V and 42 V. Good
regulation of this input supply is essential. If the input supply is more distant than a few inches from the
TPS54240 converter, the circuit may require additional bulk capacitance in addition to the ceramic bypass
capacitors. An electrolytic capacitor with a value of 100 μF is a typical choice"

 just i want to know whether i need  to add additional capacitor depends on  distant  from  input supply or not?

give me your suggestions                                                                                                                   

Sir, I am waiting for your reply
