TI recommends a 200 Hz PWM signal with a 1-100% duty cycle input to control brightness, but what is the upper frequency limit of the PWM signal?

Hi Yachi-san,
the limit of frequency is the minimum on time of the output, i recommend the minimum on time is 10us, so you can based on that and the minimum duty cycle to calculate the max frequency.
