Hello TI Experts,
Can I know if the boost switching frequency is related to the frequency of the charge pump frequency?
I met with a phenomenon that is really strange:
When VDD is 3.3V, and charge pump is abled, the input voltage is descreased to 10V,if I change the switching frequency from 400KHz to 303KHz or 629KHz, the screen flickers~
But when VDD is 5V, the input voltage is descreased to 10V,if I change the switching frequency from 400KHz to 303KHz or 629KHz, the screen willl not flicker~
