    Flasher Circuit For A White Cree XP-G

    Need help with 555 based flasher circuit for a white Cree XP-G. I would like to use this circuit to flash a white Cree XP-G with two AA batteries.



    The two AA batteries don't provide enough voltage to light the XP-G so I was hoping I could use a MicroPuck to drive the XP-G. If it is possible to use a MicroPuck in this application, I am not sure where to connect it. Should it be connected between the 2.5 vdc source and the P channel? Like this:



    Or should it be connected between the P channel and the LED? Like this:



    Any help would be greatly appreciated.

    Thanks.
