I am doing a pulses of 15us, so very quickly. I'm making a stroboscopic light to capture images of something that is spinning at 10,000rpms. The light is working but with such a low duty cycle to get a crisp image the light is pretty dim.
10,000rpms = 166.667Hz = 0.00599sec period
I want a degree or less of movement to capture the image so
0.00599sec / 360deg = 0.000016 sec per degree = 15usec flash duration
I have used a single MOSFET and I can even do ZERO resistance in series with the LED without burning it out but its still too dim. Any ideas to make it brighter?
How do I get more gate current?
