TPS61175: How to improve the efficient of the SCH

Please tell me your Vin, Vo, Maximum Io.

Please share the pcb layout to me.  if has several layer, I need to chekc the all the layer.

Please tell me how do you measure the efficiency?

The layout is vert poor. The low eff. is caused by the poor layout.
1. The input wire from 5V to inductor is thin and long.
2. The SW wire should be more short.
3. the output wire is also thin and long.
4. you should change the direction of output cap, make the GND mof the output cap and the GND of the TPS61175 directly connect together.  or the loss across the GND will be bigger.
Please refer to the TPS61175 EVM for the layout guide.
