Led driver with programmable modes

Hi there. I am looking for a kind of circuit that is LED driver with programmable pwm dim modes (non volatile memory). I have one in my hand that is bought in asia, but the name and number of the SO-8 circuit is erased. I can see that this IC is connected to the output of the led driver and just dim the LED current with a FET.

I have searched the net without finding any similar circuits.

Thanks for any advice how to find similar circuits.
