2. regarding the TLE501x PCB, in your folder I saw the PCB .lay6 but when I opened the file I saw several layout design, is any once can be used? for example I like this simple one: http://dc743.4shared.com/download/33R4BMVnce/TLE5010_PCB.jpg
In PCB what matter is the electrical connections, the "layout" or the design/form of the board can assume any practical form. Obvious short connections between components is more desirable than long.
Respecting this you can change the layout form/dimensions to fit in your project.
But the above layout don't show the components (resitor, capacitor) present in the electrical circuit - or they are in the other side of the board?
