need a 555 timer square wave generator: Here is the BOM for the 555 timer board. The output from the 555 will be .9mS High and .1mS LOW which will control a P-Channel MOSFET Gate through a 1K resistor. This timing can be accomplished using values of Ra = 115K, Rb = 15K, and C = .1uF The MOSFET should be mounted near the edge of the board with a wire pad for the 12V feeding the Source of the MOSFET. The etch should be cable of carrying 2 Amps. The Drain of the MOSFET should also have a wire pad which will be connect to the output of the supply. The higher current for the Ground will be external and not connected through the board. A wire pad will also be needed for Ground. The 555 will also be powered from the same 12V input connected to the MOSFET. The 100uF capacitor will be on the 12V supply input and to Ground on the board. board should be double sided

hello friend, i can give you a perfect solution whichever you want. I will give you a schematic in which whatever mode of 555 you want, i will made it. Also, i will care of all kind of protection like EMI, spike and proper ground. Layer of PCB will be decide as per your requirement. So, allow me to do your job.
