TPS61169: can support PWM dimming frequency 250Hz ?

Part Number: TPS61169

Hi Sir,

My customer asked some questions about the TPS61169, does it support the PWM dimming frequency at 250Hz?

If it can support the 250hz dimming, what is the range of PWM dimming signal duty cycle?

Follow the datasheet mention the PWM dimming frequency lower than 5khz, may generate audible noise. Does it have a method let us to solve this issue?
