Perhaps it could be helpful to see more,I guess an inductor is on the left, and the marking seems to be Si6FA on the second picture
 
They are two identical pcbs, one indicates Si16IK, and the other Si16FA. The final letters are the factory date.
 
I'm not sure about the specific model, but based on the inductor connected, I guess it should be a DCDC controller used for boosting or reducing voltage.
