Thanks a lot
Very valuable information in your post
would you please tell me more about the capacitor charge-discharge section of the circuit ? so i can make it and find the appropriate values . i don't know how to use capacitor for such a circuit
and why Transistor is preferred compared to...
thank you for reply
As i mentioned before, I'm using a N-channel power mosfet to drive these LEDs with logic output of uC ( Panasonic K2129 about 3A continuous and 6A in pulse current absolute rating)
It has 40ns rising time and Gate current is adjusted to make it beyond fully ON minimum current...
Thanks for your useful advises
First of all i use Chinese LED type and unfortunately i don't have any other non-Chinese choice here and these manufacturers are so weak in documenting their products .
But i used 1 watt LED with 3.5 volt FV and 200-300mA nominal Current . the problem is i get...
Hello Guys
I created nearly the same topic in microcontroller section of this forum , but not exactly the same question here ...

I'm making a high Power LED stroboscope that uses 2*10 watt LEDs Driven by micro controller with digitally...
Hello guys
Sorry for wrong topic selection and bad English
I'm working on a project with 3*10 Watt High Power LED's wich act as a frequency & duty variable stroboscope via a Micro Controller . The problem is for accurately stopping a high speed rotary device the duty should be below 2% ( as an...
hello to all ( first post )
i wanted to check a 2SC3052F and 2SA1235F in this schematic ( An AIWA HiFi )
when they tested (even out of board) everything is ok except that about 1000 ( multi tester in diode test mode ) between collector and emitter (in just one way) .
are they really broken ?
if...
