How many milliamps? The M34063 smps IC has a very simple circuit in the datasheet for a boost regulator. It only requires the IC and a few other parts.

You will get more help if you provide better information. How many milliamps do you need at 12v? What is the device that will run from 12v? Things like that.

How much current does the 12V motor need? What is its stall current?

What's the part number on the motor? There should be a ratings sticker.
