I tried several LED drivers and some of them have an undesirable behavior: at low duty-cycle levels you can notice flickering. This is not due to the actual PWM of course, but due to the driver itself.
When selecting a driver, what should I check to be sure it's flicker-free?
Unfortunately, only few of datasheets report this feature. For example ILD8150 says:
Flicker free operation
Let's say I want to select TPS92830: how to be sure the LED won't flicker?
