TPS92662-Q1: PWM Range

Part Number: TPS92662-Q1

Tool/software:

To Whom It May Concern, 

I have a question regarding the PWM range of the TPS92662-Q1.

The TPS92662's PWM is a 10-bit system for dimming, meaning it has 1,024 different levels of brightness, but the PWM frequency is not specified in the general datasheets, as the system is designed to be flexible in its application.

How low of the PWM the TPS92662-Q1 could reach? Could it reach as low as 1% PWM? Or even lower? 

Thank you in advanced for your reply.
