DIY a quadcopter, power supply problem discussion

[Diven]

Now I am DIY a quadcopter, all the programs are completed, I began to design the hardware, but the power supply has encountered some problems.

I used a 2200mah 3s lipo battery , and now the main chip power supply is 11.1V. I want to ask do you have any good way of buck power supply? Can I use the XC6206 chip?

What’s the method of your power supply?
