Hi all,
I´m working on a project for my university (industrial design) and I need to use PWM. The project is a torch with a Cree high power led (XPG), using a 6V battery. I already made the constant current regulator and it works fine.
My issue is with the PWM. The circuits I could find (most with the 555) have current output of 200mA, and I need at least 500mA for the light I want. Is there any PWM circuit I can use for these specs (~6V in, ~500mA out)?
Already thanks.
