hi Team:
if PIN 8 connect 15 v,and other PIn doesn't connect to anything,the PIN 7(out) is output high or low or Square wave?
thanks!
Hello David,
The LM5023 really was not design to have open pins, so I am not sure what out will do not knowing the status of the other pins.
If looks like you are trying to develop a test circuit and you are not sure what the output is supposed to be doing.
Could you share your test circuit with us and any waveforms you might have that you are questioning?
Regards,
Hello David,
The LM5023 is QR controller. It is going to initiate a gate drive pulse if the comp pin demands it. It is going to stay high until a peak current is reached and then turnoff.
So this could very well be a reasonable condition with only those three pins connected.
Regards,
