Hello
I built this circuit:
http://www.laro.com.pl/pdf/pt4115.pdf
I use:
Led3W I~700mA
100uF capasitor low ESR
Schottky SS16
Rs 0.13Ω
coil 100uH
I dont use these four diodes for the bridge, because I use a DC power supply.
For dimming I used mC and a function generator. As far as I understand if I just leave this pin, it should be always on. Right?
I lost a few circuits, because it makes a short between GND and SW. The diode just blinks and thats it.
What can be wrong? A component I use? Or smt is wrong in my circuit?
