![]() This pin outputs the PWM signal based on the feedback provided and we can use this to switch the power electronic device. ![]() The IC has an internal oscillator which can be set using an external Resistor and capacitor connected to this pin. RT/CT (Timing Resistor/ Timing Capacitor) The difference in voltage level is supplied to this pinĪ shunt resistor is used to monitor the current through the circuit and the voltage across it is provided as a feedback to the current sense pin It is an input to the error amplifier that inside the IC. It is normally connected to the voltage feedback pin of the IC through resistor and capacitor. It is an output pin which outputs low impedance 1MHz single based in the difference between he set and current voltage. ![]()
