Posted:If I wanted to make a ( 3w RGB LED module ) -blink- about 60 times per second, what driver would allow me to do that in unison with a 3.7 volt 1000mAh battery (DC)? These LEDs are -current driven- at 350ma, which means that I have the drivers which run them at 350ma, but I just want them to blink fast.
I am a DIY'er and would love to be able to mod this myself so these LEDs will blink fast. Cheap solution?
I have checked into the 555 timer but the maximum output allowed for this unit is 200ma where as I need 350ma for maximum brightness.
I think I'm thinking of this in a different way than you. Could you explain a little more please? I'm not sure how the power transistor would work to oscillate the frequency and make the LED blink from an inline resistor fed to the power transistor. I am confused on how this would work. I've never used power transistors.
