Hi,
Im Driving two power MOSFETs (stp36nf06) using a SG3525ANG with a gate resistor, when I measure the Gate-Source voltage using the oscilloscope I get a perfect PWM of a peak-peak of 12V, but when I tried to measure the Drain-Source voltage I got a flat DC line at 12V with small spikes at the points its suppose to be switched off! I dont know what the problem is! I know im suppose to get a PWM between the drain and the source! any idea what the problem might be?
Regards,
