TPS54200: TPS54200 PWM Frequency Range (analog dimming)

Lee Do Hyung
Prodigy 10 points
Part Number: TPS54200

Tool/software:

Hi, TI Expert.

I'm using TPS54200 for IRLED driving.

Driving mode is analog dimming mode.

For some reason, i want to change PWM frequency during operating.

Expected frequency range is 20kHz ~ 50kHz.

Is it fine changing PWM frequency during operating without any acting? (for example rebooting IC...)

And another question is spec of PWM frequency.

In 8.4.3  Analog Dimming Mode Operation of datasheet PWM frequency is recommended to set higher than 10kHz.

But, as far as i found, there is no clear mention of frequecny range of PWM.

Would you let me know min, max specificaiton?

Thank you.
