Hello,
In reading the datasheet for TL7660, there is a section on changing the clock frequency. For overclocking the frequency it shows a figure connected with an appropriate resistor to the clock pin, then for underclocking the frequency it shows a capacitor being placed between the clock pin and the Vcc. My questions are as follows:
1) What is the minimum clock frequency allowed before there are issues with the functioning of the device?
2) Is it possible to use a PWM signal or analog timing circuit to lower the frequency as low as 10-100 Hz?
3) If not is it possible to use the capacitor -- Vcc scheme to do so?
Thanks!
