I have this IC - Advance regulating PWM
I would like to understand how does the timing resistor and capacitor section works. Sorry for the beginner question but I am unable to understand this section.
The resistor in the RC circuit, will determine the rate of capacitor charging and discharging and that too when R and C are connected in series.
But in this IC, it is given as The timing capacitor provides the ramp signal. How does the charging and discharging of the capacitor take place? I dont see the timing resistor part involved in doing this. Can someone please explain clearly.
