i can't get the control voltage (V11)from pin 11 in the straight line waveform when i connected the as the datasheet given. The synchronization voltage (V5) and the Ramp voltage (V10) i can get it as the datasheet stated . But the Control voltage (V11) i cant get it asstraight line as the data sheet stated. Which point i need to check for my circuits ?? HELP PLS... URGENT as the project due date is closer. Thanks
