TPS92641 UDIM PWM frequency

Other Parts Discussed in Thread: TPS92641, TPS92641EVM
Hello,
Is there a recommended frequency range when using UDIM for PWM dimming of TPS92641? In the data sheet I can only find 200 Hz (mentioned in figure 12 on page 8):

Same thing with the User's Guide for the TPS92641EVM (table 1, page 2):

I would not mind using a slightly higher PWM frequency than that. Especially since I got a tradeoff between PWM frequency and PWM resolution due to HW limitations in the control MCU.
Best Regards,
