TPS92520-Q1: dimming range

We have a 10 bit PWM dimming register so you can use have a 1 bit resolution out of a 1024 bits (~0.1%), but keep in mind the linearity of the average LED current gets worse at really low duty cycles.   

Here is some training videos so that you can get familiar with LED driving techniques and information.  It covers PWM dimming and also shunt fet dimming.
