Hello! I need some help. Maybe here are any audio electronics engineers. I need help with type of impulse power supply driver circuit type. Impulse power supply doesn't work, I checked by scope, that there is not driving signal on swiching mosfets transistors. There is small circuit (8-pins DIP) generating impulse signal for controlling power supply and there is any marker on it. Can anybody help me? I need datasheet and pinout of this circuit, but I don't know what is it Sorry for my english I'm writting from Poland.
